P2.3.1 Energy and Work 0.0 / 5 ? PhysicsWork, energy and Momentum.GCSEAQA Created by: MaddiCreated on: 24-04-14 21:38 What do we mean by 'work' in science? Work is done on an object when a force makes the object move. 1 of 5 What is the relationship between work and energy? Energy transferred = Work done 2 of 5 How do we calculate the work done by a force? Work done (Joules) = force (newtons) x distance moved in the direction of the force (metres). 3 of 5 What are the units for work done, the units for newtons and the units for distance. Work done: J. Force: N. Distance: m. 4 of 5 What happens to the work done to overcome friction? Work done to overcome friction is transferred as energy that heats the objects that rub together and the surroundings. 5 of 5
