Work, energy and momentum 0.0 / 5 ? PhysicsForces and MotionGCSEAQA Created by: JordanScammellCreated on: 23-03-14 14:47 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 5 of 5
