Work and Power 0.0 / 5 ? PhysicsWork and PowerGCSEAQA Created by: emewsCreated on: 23-11-17 17:35 What is the equation for GPE? GPE = m x g x h 1 of 9 The amount of GPE an object on Earth has depends on its: Height above the ground and its mass 2 of 9 True or false? On Earth we always have the force of gravity acting on us. TRUE! 3 of 9 The KE an object has depends on its: Speed and mass. 4 of 9 What is the kinetic energy equation? KE = 1/2 x m x (v x v) 5 of 9 When is work done? Work is done whenever a force moves something 6 of 9 What is the equation for work done? work done = force x distance 7 of 9 Give an example of when work is done. Everyday examples of work include walking up stairs, lifting heavy objects, pulling a sledge and pushing a shopping trolley. 8 of 9 What happens whenever work is done? Whenever work is done, energy is transferred from one place to another. 9 of 9
