From work to energy
From work to energy
Work done is energy transferred when a force moves an object through a distance in the direction of the force. For a constant force, W=FxW = FxW=Fx, and this idea leads directly to both kinetic and gravitational potential energy.
Step-by-step lessons on OCR A A Level Physics Kinetic and potential energies. Each one builds up to exam-style questions. Physics is one of the most mathematically demanding A Levels -- at least 40% of the marks across the three papers require maths skills at Level 2 (GCSE) standard or above, so build calculation and graph-handling fluency alongside the conceptual content from the start.
