Types of energy store Flashcards
1
Q
Where is thermal energy stored
A
In the vibrations between particles
2
Q
Where is chemical energy stored
A
In the bonds between particles
3
Q
When is elastic potential energy stored
A
when an elastic object changes shape in a reversible way (Streching/Squashing stores energy)
4
Q
When is gravitational potential energy stored
A
When an object is moved higher than or away from a gravitation field
5
Q
what the equasion for kinetic energy
A
Kinetic energy = 1/2mass x velocity
6
Q
whats the equasion for gravitational potential energy
A
Gravitational potential energy = mass x gravitational field x height
7
Q
whats the equasion for elastic potential energy
A
elastic potential energy = 1/2 x force x extension of the spring
