Potential and kinetic energy Flashcards
1
Q
what is potential energy
A
it is energy stored in objects
2
Q
what is kinetic energy
A
it is energy in moving objects
3
Q
what is GPE
A
GPE is potential energy stored in objects above the earths surface
4
Q
what are the two factors that affect GPE
A
height and mass
5
Q
what are the two factors that affect the KE of an object
A
velocity and mass
6
Q
how does energy change in falling objects → in 3 dot points
A
- object is held at the highest point, highest GPE, no KE
- as it falls, it looses height, the GPE present in the object is transformed into KE
- when the object reaches the ground all its GPE has been transformed into KE
