lesson 3 gravitational potential energy (epe) Flashcards
1
Q
what is gravitational potential energy
A
the energy stored in an object due to its position above the earths surface
2
Q
what is the equation for gravitational potential energy
A
Ep= m g h
3
Q
what is ‘gpe’ measured in (gravitational potential energy)
A
J (joules)
4
Q
what is ‘m’ measured in (mass)
A
kg (kilogram)
5
Q
what is ‘g’ measured in (gravitational field strength)
A
N/Kg (newtons per kilogram)
6
Q
what is the ‘h’ measured in (height)
A
M (metres)
7
Q
why is gpe occuring
A
due to the force of gravity acting upon the object
