Revise OCR GCSE Physics 7.1.5 Kinetic, elastic and gravitational potential energy with the question bank and revision guides.
calculate the amounts of energy associated with a moving body, a stretched spring and an object raised above ground level; Practical (PAG P5 Energy): use light gates and trolleys to investigate kinetic energy; use a joulemeter and motor lifting a weight to investigate gravitational potential energy; investigate the energy changes and efficiency of bouncy balls.
