Force and Motion blog By Ethan Catoe       Force is something that can be described as a push or pull object. Force is always being made and used for example, i'm using force right know by as i am typing this blog because i am applying force to the keys on the laptop with my fingers causing it to transfer the words onto the screen. Even though push and pull forces are one of the main talked about forces,there are many more forces that can be talked about like contact force, friction, inertia, non - contact forces, and motion. The type of force that i am focusing on is contact forces. contact forces are forces when 2 objects are physically interacting with each other by touching. There are many different contact forces like normal force, spring force, applied and tension force. normal force is when there is nothing moving,spring force is created by a compressed or stretched spring that could push or pull. Applied force is when someone is applying a forc...

Preeti Gurung Date- 12/19/2018 Blog We see newton's law applied everywhere. However, the newton's law reaction is harmful or useful.According to the third Newton's law: every action has an equal and opposite reaction. Then, both action should get cancelled and the body should remain constant. My question is, why does a bullet move from a gun according to this law? Rifle and bullet together form since when they are in contact. So, they have newton's third law applied to them . Since, the bullet is inside the gun, they came contact with each other before the bullet was fired, that means (they are part of the systems) As soon as a bullet is fired the chemical reaction would take place that rapidly cause the gunpowder which expands pushing it from its shell - once again bullet and shell form a system. Shell heats up, and bullet gains energy and the bullet which expands out of the gun.We can recast Newton's third law from forces to change in momentum. Momentum is define...

Europe's Hyperloop Train By Luke Phillips Recently in Switzerland a plan got put into motion to build a Hyperloop. The Hyperloop is a design created by Elon Musk for a high speed travel machine. While it will be a quite expensive project, the Hyperloop can travel at speeds of 560 miles per hour. This is comparable to the speed of a Boeing 747. This Hyperloop works by using electromagnets to push the Hyperloop into a vacuum. This vacuum isn't totally void of air however. It has low air pressure inside of the tube that when the pod moves into it compresses. Normally when air compresses it slows the thing compressing it, but the pod has a fan on the front of it to let the compressed air into it. The air is then jettisoned through the bottom of the tube to keep it off the walls of the Hyperloop, reducing friction.  The Hyperloop could be the transportation of the future if proper funding were to be received for it. Not only is it fast and efficient travel, it also is self s...

The effects of air resistance on objects By Ayad Alhazmi According to NASA, “Drag is a mechanical force. It is generated by the interaction and contact of a solid body with a fluid (liquid or gas)”. Think about it like “air friction”, another way of saying air resistance is drag. The term drag is used commonly with aerodynamics. It is an element of a plane/jet. The four elements of a plane/ jet is lift, weight, thrust, and drag. Drag is very important when it comes to flight. If you can’t overcome drag then your plane goes backwards. The only way to overcome drag is with thrust. As stated previously drag is a term used for planes and jets. But, air resistance is the general term. For example the wind is blowing against you as you run, so to run the same speed if the wind was not blowing as hard it would take more energy. Another example is driving a car in a rainy day. When it is raining outside, the wind blows hard, if someone was to drive the car in the opposite direction it will ne...

Force and Motion in Baseball Arden Jansen  Baseball has been using up in coming technology to track the  performance  of every player. It is not just a traditional  timing  gun but instead tracks the balls route. Instead of the fans being the only ones to watch the game, the virtual camera tracks it too. This is not just a tremendous help in improving the pitcher’s skills but instead the  batters . Interesting enough, there is tons of science behind the game itself.   Physics is a large  component  of the sport baseball. The definition of physics is the study of energy and objects in motion.  Computer  programs  have the ability to  capture the data and  analyze  the pitch. When  critiquing  the batter, they can see what type of pitch made the ball  travel  farther than another .  These  factors  differentiate  the players with  facts instead of opinions. Eve...

Marina W 12-16-18 Magnet Physics Magnets are a common household product in many places. You can find them on refrigerators, mirrors, and on the occasional car. But delve deeper than that and they are everywhere. Refrigerator doors, treadmills, vacuum cleaners, computers, and even phones use magnets to function properly. Although magnets are so common, most people don’t know the science of how it works. They are made of metal, and while the type can vary, they all have an invisible magnetic field that surrounds them. One fact about magnets is that they only work on motion. A single particle with an electric charge that is simply existing, will generate an electric field. This field surrounds the particle on all sides and affects the movement of particles around it. If a similarly charged particle is nearby, it will be pushed away. If an oppositely charged particle is far away, it will be drawn towards it. But if you move that electric particle, a new field is generated. This new field i...

Force and Motion Blog  By Amadi Clemens INTRODUCTION: Do you listen to Travis Scott? If so, you know of his most recent album AstroWorld has been on tour. One of his recent shows (in Oakland, California) he performed with a roller coaster. Crazy, right? It wasn’t like a full roller coaster that you see Six Flags. It’s like the Ring of Fire at Clementon Park. His ring ties into his theme park theme! PROS AND CONS: There are pros and cons that follow this event. A pro is that it was a fresh idea. I’ve seen amusement parks and rides in music videos but never live in concert. Another pro is that it was eye-catching and entertaining.. The main idea of a concert is that it is entertaining, this is going back to the idea of fresh. A con is that it’s very dangerous. Although thrilling, what if something goes wrong? What if it breaks? What if it stops mid-way in the year and he can’t rap anymore? Mechanical service would have to come and get him and that can ruin the concert. Another con, ...

Alice Bazyar Gateways Force and Motion Blog December 17th, 2018 Watch an Astronaut Test Newton's Second Law of Motion in Space In a recent video, NASA’s astronaut Randy Bresnik, declare the most newest installment of NASA’s educational series STEMonstrations and shows the connection between Newton’s second law of motion by sending three objects into a free flight in the International Space Station. STEMonstrations is presented by astronauts living in the space station. NASA brings in sponsors from 6th, 7th, and 8th graders and shows their educational videos done by the professional astronauts. What is Newton’s second law of motion? “Newton's second law of motion pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.” according to https://www.physicsclassroom.com/class/newtlaws/Lesson-3/Newton-s-...

Newton's Laws: Spongebob Patrick Getting Beat Up By Nothing Made No Sense! By Marc Gabay In one of the older episodes of Spongebob, Patrick tried to make Spongebob feel better by "beating himself up". He then somehow starts to magically float and being was being slammed around by nothing. This was a direct violation of the laws of physics; as Patrick definitely shouldn't be able to float in the air. Yeah, sure, it takes place underwater, but he should still be floating down, not being stationary in the "air". Patrick then proceeds to spin around rapidly somehow. Next, he gets slammed around out of no where with Spongebob just watching idly. In the end of the scene, Patrick gets a floating wedgie, which should hurt, and gets kicked a few miles away, which also makes no sense as no one can fly a few miles from one hit from anything. We all know this is a cartoon logic and physics don't apply and can't be questioned, but it's easy to tell i...

Force and Motion By: Chris Anderson For every action, there is an equal and opposite reaction. This is Newton's 3rd and probably most famous law. His laws apply to every thing, from you to the Sun. Most forces are apply by contact with an object such as pushing/pulling something, or lifting something but there are more than those. Things like gravitational forces and magnetic forces don't need to be in direct contact with an object to effect it.Every type of matter can produce a force as long as it has energy. Energy is the ability to do work. Friction and air resistance are two things that oppose motion. For example, when you run, you are creating friction on the ground by stepping on it, then you are pushing yourself of of the ground. On surfaces like ice however, they are very smooth and have little to no friction. So if you sent something on ice, it would keep going and going and going. Researchers at Southern Methodist University have found new concepts in human...

Zach Fluck Science blog Force and Motion Blog Sir Isaac Newton was an English astronomer, physicist, and mathematician, born on December 25, 1642. He died on March 20, 1727, most likely from mercury poisoning or old age. However, during his life, he made several contributions to modern science and advanced our understanding of physics tremendously. Arguably his most famous discovery was gravity. However, he had to use his 3 laws of motion to make this accomplishment. Newton understood that an object at rest will stay at rest, unless acted on by unbalanced forces. Therefore, if an object such as an apple is in a resting position there must be a force to make the apple fall to the ground. He discovered this invisible force to be gravity. At a young age Newton was removed from school to be a farmhand. Despite returning to school the turning point in his live was he left his hometown to attend Cambridge University. After attending Cambridge he returned to his hometown where his observat...

A computer artist's view of what InSight looked like when it touched down. Try Landing InSight on Mars By: Chris Tyburski     Recently, NASA successfully landed the rover, InSight, on Mars. This landing was very important for NASA, many rovers in the past breaking on impact. The InSight rover will spend a few years collecting important data about the terrain, and will help us figure out if the Red Planet is adequate for human life.      However, this important milestone was not easy to achieve. As mentioned, NASA has had great difficulty successfully landing rovers in the past. This article details all of the different factors scientists had to take into account when planning this landing on Mars.      First, the gravity on Mars is very different from that on Earth so they had to use different calculations then that on Earth. Because of this, NASA could not do test landings here on Earth to make sure the landing would be succes...

Gravity By Sam Irani        Why do you land on the ground when you jump up instead of floating off into space? Why do things fall down when you throw them or drop them? The answer is gravity: an invisible force that pulls objects toward each other. Earth's gravity is what keeps you on the ground and what makes things fall.  Gravity  is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun.          Anything that has mass also has gravity. Objects with more mass have more gravity. Gravity also gets weaker with distance, so the closer objects are to each other, the stronger their gravitational pull is. Earth's gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body which gives you weight. And if you were on a planet with less mass than Earth, you would weigh less than you do here. ...

 Force and Motions Sky Diving                                                         By:  Alzahra   Alrubaiey         Sky diving is a sport of jumping from an aircraft and landing on the ground with a  parachute . The physics behind skydiving involves the interaction between gravity and air resistance. When a  skydiver  jumps out of a plane they  start to   accelerate  downwards, until they  reach  a certain  speed. This is the speed at which the drag from air resistance exactly balances the force of gravity pulling him down. As the skydiver falls faster and faster, the amount of air resistance increases more and more.  ...
