Kinetic and potential stores Flashcards
1
Q
What is a Kinetic energy store?
A
Any object that moves and has motions
2
Q
What does kinetic energy depend on
A
Mass
Speed
3
Q
The equation for Kinetic energy
A
1/2 x Mass x Velocity2
4
Q
What is a gravitational potential store?
A
Any object raised in a gravitational field
5
Q
Gravitational potential depends on…
A
Mass
Height
6
Q
The equation for gravitational potential
A
Mass x Gravitational field strength x Height
7
Q
What happens to the energy stores of falling objects?
A
The energy lost from the gravitational potential store equals the energy gained in the kinetic energy store.
This is because the further the object falls, the faster it goes.
8
Q
The equation for Elastic potential energy
A
1/2 x Spring constant x Extension2
