Find the kinetic energy k of a satellite with mass m in a circular orbit with radius r. express your answer in terms of m, m, g, and r.

Explanation:

The kinetic energy is defined as:

Here, m is the object's mass and v its speed. In this case the speed of the satellite is the orbital speed, which is given by:

Here, G is the gravitational constant, M is the mass of the object that the satellite is orbiting and R is the radius of its circular orbit. Replacing (2) in (1):

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.

scientific laws are the result of testing theories and proving them to be facts.
