# Potential and Kinetic Energy

1. How much potential energy does an object have that has a mss of 10 kg and is 4 meters off the ground on earth?

2. How much potential energy does an object have that has a mass of 10 kg and is 4 meters off the ground on the moon where gravity is 1.6(m/s^2)?

3. If the object falls half way to the ground so that its height is 2m, how much total energy will it have?

4. How much potential energy does it have at a height of 2 meters?

5. How much kinetic energy does it have at 2 meters?

6. If an object is not moving, how much kinetic energy does it have?

1. How much potential energy does an object have that has a mass of 10 kg and is 4 meters off the ground on earth?

Potential energy = m g h

m= 10 Kg

g= 9.81 m/s^2

h= 4 m

Therefore PE = mgh = 10 x 9.81 x 4 = 392.4 J
