Energy, Work & Power Past Paper Questions for A Level Mechanics (9709)

Studying for your mechanics A level?

On this page you'll find plenty of questions on kinetic energy, gravitational potential energy, work done, and power from Cambridge A Level past papers.

You'll need to calculate the work done by a constant force, even when displacement isn't parallel to the force.

Know how to apply formulae for kinetic and potential energy, and use conservation of energy to relate changes in energy to work done by external forces.

Understand power as the rate of doing work, and use the link between power, force and velocity when the force acts in the direction of motion.

Questions may involve scenarios like a car accelerating uphill against resistance.
