Edexcel International GCSE Physics4c Work and power Checklist

Papers 1 and 2

• I know and can use the relationship between work done, force and distance moved in the direction of the force: work done = force × distance moved, W = F × d
• I know that the work done is equal to the energy transferred.
• I know and can use the relationship between gravitational potential energy, mass, gravitational field strength and height: gravitational potential energy = mass × gravitational field strength × height, GPE = m × g × h
• I know and can use the relationship kinetic energy = ½ × mass × speed², KE = ½ × m × v²
• I understand how the conservation of energy links gravitational potential energy, kinetic energy and work.
• I can describe power as the rate of transfer of energy or the rate of doing work.
• I can use the relationship between power, work done (energy transferred) and time taken: power = work done / time taken, P = W / t
