One application of the law of gravity is to figure out how to put a satellite into orbit so that it remains in the same position relative to ground all the time. A satellite in such a position can be ...

Answer: the critical speed occurs when the acceleration of the water due to gravity equals the centripetal acceleration, that is when g equals velocity squared divided by radius. This clip will be ...

The normal component of acceleration is known as the "centripetal" component. It is proportional to the square of the speed, and inversely proportional to the radius of curvature of the path. The ...
