Module 3:

Section 3.5 Newton's laws of motion and momentum

3.5.1 Newton's laws of motion	(a) Newton's three laws of motion
	(b) linear momentum; vector nature of momentum p = mv
	(c) net force = rate of change of momentum; F = ΔP/Δt	You are expected to know that F = ma is a special case of this equation.
	(d) impulse of a force; impulse = FΔt	You will also be expected to estimate the area under non-linear graphs and use a spreadsheet to determine impulse from F–t graph.
	(e) impulse is equal to the area under a force–time graph.
3.5.2 Collisions	(a) the principle of conservation of momentum	Multiple Choice Structured Questions	Two-dimensional problems will only be assessed at A level.
	(b) collisions and interaction of bodies in one dimension and in two dimensions
	(c) perfectly elastic collision and inelastic collision.
