... around Earth rather than onto it. Once it has entered a stable orbit, a satellite does not need fuel. It continues to move ahead due to its inertia. At the same time, gravity continuously changes the satellite’s direction. Most satellites are launched at a speed of about 7,900 m/s. That’s more than ...

Homework 2 Solution
... This looks unpromising; the first part looks like what we are after, but there is an extra factor of v 2 , and the second looks like a mess. But a miracle happens. With a little algebra: γ −2 v 2 (1 − γ 2 )2 = ...

3 Conservation of Mechanical Energy II: Springs, Rotational Kinetic
... an object is spinning, every bit of matter making up the object is moving in a circle (except for those bits on the axis of rotation). Thus, every bit of matter making up the object has some kinetic energy 12 mv 2 where the v is the speed of the bit of matter in question and m is its mass. The thing ...
