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 need more gasoline to drive the same pace as if it was a sunny day.

There is three main types of air resistance (or drag), vortices derive, Lift Induced, Parasitic, and Wave drag, and parasitic drag. Vortices derive is mixed air in a variety of pressures and that is needed to create lift. As the lift of the aircraft increases, so does the lift induced drag. The second type of air resistance is Lift Induced, Parasitic. As previously stated, as the lift from the aircraft increases, so does the lift induced drag; lift induced drag is how the object reacts to the high pressure of air resistance. Have you seen an airplane fly of? If you have you would see the airplane go to a inverted position and you think it’s not right, but that is the result of lift induced drag. The last type of air resistance is Wave drag. Wave drag is drag that is caused when an object moves through the air at such high speeds. An example of wave drag is a jet breaking the sound barrier, when a jet breaks the sound barrier the boost of a jet creates a loud boom, this is called a sonic boom.Those are the three main types of air resistance.

The next steps of this research is to see if when breaking the sound barrier, is there drag. The research will have to gather more data on wave drag. They should also make an experiment with a drone and gather data on the drag. Then after the multiple trials scientist should try to make a different design of a drone. If it succeeds through another three trials it should be a new design of a jet that can create less drag.

Force and Motion in Concerts

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, what

Chemical complexities that causes Saturn's rings to change planet’s atmosphere

Ayad Alhazmi 10/19/2018 Chemical complexities that causes Saturn's rings to change planet’s atmosphere New discoveries are made today on Saturn's rings by the Cassini space probe. Based on data from the final orbits of NASA's Cassini space probe shows the rings of Saturn. Some of the most amazing celestial objects in the universe are far more chemically complicated than was previously understood by scientist. When the Cassini space probe first gathered the information from 2017 and the signals of Cassini took scientist a long time to retrieve the information. Also knowing the astrophysicists are still studying it is beyond my reach. I will show you a quote by a professor of physics and astronomy Thomas Cravens. "Two things surprised me. One is the chemical complexity of what was coming off the rings -- we thought it would be almost entirely water based on what we saw in the past. The second thing is the sheer quantity of it -- a lot more than we originally expected.

The Earth is a very big Magnet Its North and South Poles are Highly Magnetic

The Earth is a very big Magnet     Its North and South Poles are Highly Magnetic   By: Alzahraa Alrubaiey Magnetism is the force exerted by magnets when they attract or repel each other. Magnetism is caused by the motion of electric charges. Earth has two geographic poles: the North Pole and the South Pole. They are the places on Earth's surface that Earth's imaginary spin axis passes through. Our planet also has two magnetic poles: the North Magnetic Pole and the South Magnetic Pole. The magnetic poles are near, but not quite in the same place as the geographic poles.   The Earth is a magnet that can interact with other magnets in this way, so the north end of a compass magnet is drawn to align with the Earth's magnetic field. Because the Earth's magnetic North Pole attracts the north ends of other magnets, it is technically the South Pole of our planet's magnetic field. A compass point north because all magnets have two poles, a north pole
