Work, energy and momentum

HideShow resource information
What happens when a force moves an object?
Energy is transferred and work is done.
1 of 5
Equation: work done.
W = F x d (j = N x m)
2 of 5
How can work be done to overcome friction?
Work done is transferred as energy that heats the objects that rub together and the surroundings.
3 of 5
What is gravitational potential energy?
Energy stored in an object because of its position in the Earth's gravitational field.
4 of 5
Equation: change in gravitational potential energy.
E(p) = m x
