AQA GCSE New Specification 8463 Unit 1.2 Energy: Work done and Energy 3 of 9

Lesson Objective
To learn about forces, the work that they do and how to measure it.

Lesson Outcomes
Core level 4:
State that energy is measured in joules (J).
Calculate the work done by a force.
Measure the work done by a force experimentally.

Challenge level 6:
Describe the action of frictional forces on objects and the associated heating effect.
Use the equation for work done to calculate distances or size of forces.
Use repeat values to measure the work done by a force experimentally.

Aspire Level 8:
Use the principle of conservation of energy and forces to explain why objects become heated by frictional forces.
Apply the equation for work done in a wide range of contexts.
Evaluate in detail an experiment to measure work done, explaining why there is variation in the measurements.
