Topic 4 - Kinetic and Potential Energy Flashcards
1
Q
anything thats moving has energy in its…
A
kinetic energy store
2
Q
what does the energy in the kinetic store depend on?
A
the object’s mass and speed
3
Q
what is the formula for energy in kinetic energy store?
A
energy in kinetic store = 1/2 x mass x (speed)²
4
Q
what does the energy in the GPE store depend on?
A
the mass of the object, height and the gravitational field strength
5
Q
what is the formula for energy in the GPE store?
A
energy in GPE store = mass x gravitational field strength x height
6
Q
what energy transfer happens as an object falls?
A
energy from the GPE store is transferred to the kinetic store
