A ball is thrown up in the air. When does the ball have 0 Joules of kinetic energy?
At the height of the throw, just before the ball starts going down.
Increase the mass or decrease the distance.
KE = 1/2mv2

Explain the gravitational interaction between the Earth and the moon.
The Earth's gravity maintains the moon's orbit. The moon also pulls on the Earth and makes it wobble.
KE = 1/2mv2
