Potential Energy Flashcards
1
Q
define PE
A
an object can have PE because of its location ( where a force can act on it) or because of its structure
2
Q
what are some examples of elastic potential energy
A
elastic band when stretched, a trampoline at its lowest point
3
Q
explain when a tennis ball has elastic potential energy
A
when its compressed on a racket and is about to bounce back
4
Q
what type of PE does food and petrol have
A
chemical
5
Q
What is gravitational potential energy
A
an object that is raised above a reference point in a gravitational field has GPE. If the object falls it will accelerate and GPE will transform into KE.
