 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.  
Isaac Newton’s laws are also related to skydiving. Newton's Second Law of Motion states that the more massive an object is, the more force is required to move the object, or to stop the object. This law affects skydiving because the more massive a skydiver is, the more force will have to be applied by air resistance. Newton’s third law of motion is for every action there is an equal or opposite reaction. This law is important in skydiving because when the skydiver is falling they are accelerating until they open their parachute which will slow them. If the skydiver does not open a parachute, they will hit the ground with a large force, and the ground will hit them with an equal force. 

 Newton's First Law of Motion states that an object at rest remains at rest unless acted upon by an unbalanced force. It also states that an object in motion remains in motion and at a constant velocity unless acted upon by unbalanced force. Without this law skydiving would never exist. If gravity were not acting upon the skydivers, they will not continue moving in the same direction. 


The future of skydiving is very bright. The free fall camera is a new smart robot camera that’s designed to autonomously film skydivers as they leap out of airplanes thousands of feet in the air. This camera can make sure that all the skydivers land safely on the ground. Skydiving in the future might not have parachutes, scientists can develop some new ways for skydivers to land safely on the ground. Or they can also change the way that the parachutes is designed.

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
