Chapter 3- Gravitational Potential Energy Stores Flashcards
1
Q
What is the gravitational potential energy?
A
The gravitational potential energy store of an object increases when it is lifted up because work is done on it to overcome the gravitational force.
2
Q
How does the gravitational field strength differ?
A
The gravitational field strength at the surface of the Moon is less than on the Earth.
3
Q
What is the equation of the change in gravitational energy store?
A
The change in the gravitational potential energy store of an object is AEp=m g Ah
4
Q
Describe gravitational potential energy?
A
The gravitational potential energy store of an object increases when it moves up and decreases when it moves down.
