AQA GCSE Physics - Work, Energy, Momentum Again confusing Again lots of questions :) 4.0 / 5 based on 13 ratings ? PhysicsForces and MotionGCSEAQA Created by: Carol JonesCreated on: 10-06-09 08:48 Work done is measured in ... J 1 of 6 Kinetic Energy/KE is ... 1/2 x Mass x Speed squared 2 of 6 What is KE? Energy of a moving object dues to it's motion 3 of 6 Momentum/P is ... Conserved whenever objects interact, provided no external forces act on them 4 of 6 How do you work out recoil velocity? (mass A x velocity A)= -(mass B x velocity B) 5 of 6 when 2 objects move apart, do they move apart with equal and opposite momentum? Yes 6 of 6
