Why do objects have GPE?
When they have a potential to fall e.g. A man standing on a diving board
1 of 10
Name the two factors that increases the amount of GPE an object has.
1.) its MASS 2.) its position on the earths gravitational field (HEIGHT ABOVE GROUND)
2 of 10
Give the equation for GPE
GPE= mgh (m= mass in kg, h= vertical height in m, g= gravitational field strength in N/Kg (10N/kg on earth))
3 of 10
When an object falls, it converts.....
GPE into kinetic energy
4 of 10
If the MASS of a rollercoaster DOUBLES, the kinetic energy.....
Also DOUBLES
5 of 10
If the SPEED of a rollercoaster DOUBLES, the kinetic energy.....
QUADRUPLES

Explain the energy transfer between GPE and KE on a rollercoaster
The cars start high up with a lot of GPE, as the cars drop the GPE is gradually transferred to KE, at the bottom of the slope, the car reaches its highest speed and therefore max KE, as the car climbs back up other side the KE is converted back- GPE
7 of 10
Kinetic energy =
1/2 mv^2
8 of 10
If ALL the GPE is converted to KE..... give the formula
mgh = 1/2 mv^2
9 of 10
the m on each side cancels and can then be rearranged to give the height.....
h = v^2 / 2g
