An object held _____ the ground as GPE
above
below
The amount of GPE an object on Earth has depends on its:
Mass
Height above the ground
Size of object
Surface area
GPE =
mgh
abc
mjc
mgw
h = the change in height in metres, m
A bouncing ball converts GPE into...
Kinetic energy
Gravity
Air resistance
It doesn't return to it's original height because:
energy is lost
energy is transferred
KE =
½ mv^2
mv^2
½mv x 2
The riders at the top of a roller coaster ride have a lot of...
Gravitational Potential Energy
When the train is released, the energy in converted into...
Kinetic Energy
mgh = ½ mv2
Why?
because KE = GPE
because they are balanced
The KE of an object depends on:
Speed
Weight
Surface Area
