3.20 uniform circular motion
This storyboard does not have a description.
There once was a woman who dreamt of launching a satellite into Earth's orbit.
She dedicated most of her time studying the different forces that applied to objects in outer space.
I wonder what I have to do to keep my satellite in uniform circular motion, the motion of an object in a circle at a constant speed, around earth?
She realized that the forces governing the earth, moon, and other planets, which are all natural satellites, would also apply to her satellite!
For her satellite to orbit the earth, it would have to travel a horizontal distance of 8000 meters before falling a vertical distance of 5 meters. Because of the earth's curve, the satellite would remain the same distance above the earth.
The net force that keeps the satellite orbiting earth is caused by gravity, creating an inward or centripetal force. The orbit makes the satellite have a tangential velocity, meaning that the direction of the velocity vector at any instant is in the direction of a tangent line drawn to the circle (orbit) at the object's location.
