Forces

Forces and their interactions

Describe scalar and vector quantities, contact and non-contact forces, weight, gravity and resultant forces.

Work done and energy transfer

Link work done by forces to energy transfer and calculate work done using force and distance.

Forces and elasticity

Describe elastic deformation, Hooke's law, spring constant and elastic potential energy.

Moments, levers and gears (physics only)

Explain turning effects, moments, levers and gears for physics-only content.

Pressure and pressure differences in fluids (physics only)

Explain pressure in solids and fluids, pressure differences with depth, upthrust and atmospheric pressure for physics-only content.

Forces and motion

Describe motion along a line, interpret motion graphs, calculate acceleration and apply Newton's laws.

Momentum

Describe momentum, conservation of momentum and force as rate of change of momentum for HT physics content.
