Newton's first law is known as the law of inertia. It states that an object in motion will stay in motion until an external force acts on it. In the cell above, a satellite is moving at 7000 mph in space.
In the next cell, the satellite is still moving at 7000 mph in accordance to newton's 1st law of motion. It kept moving because there is no air resistance and no external force, like a planet or asteroid or any obstacle it could have encountered in the 20 years.
Aboard the ISS
In the third cell is demonstrating newton's 2nd law of motion. It states that the acceleration of an object is produced by the net force applied on it. And in the cell, the rocket is lifting off, or accelerating. In the cell it is currently at a speed of 100 mph.
The the fourth cell, the rocket shown in cell three, is still accelerating and is now at it's top speed: 25000 mph according to newton's 2nd law of motion. It will then stop accelerating as it approaches the ISS.
SPEED: 25,000 mph
In the fifth cell -which is aboard the ISS- newton's third law is being demonstrated. It states that every action (force) has an equal and opposite reaction (force). Because there is no gravity, there are no up and down forces. When the ball hits the other ball, it stops, transferring it's energy into the other ball.
The sixth cell is a continuation of the fifth. Newton's third law is causing all the energy now transferred into the second ball to make the ball move the same way as the first ball. this demonstrates the action (the first ball), and the reaction (the second ball).
