# Momentum – Further Mechanics Paper 3

Candidates should be able to:

• recall Newton’s experimental law and the definition of the coefficient of restitution, the property $$0 \leqslant e \leqslant 1$$, and the meaning of the terms ‘perfectly elastic’ $$(e = 1)$$ and ‘inelastic’ $$(e = 0)$$
• use conservation of linear momentum and/or Newton’s experimental law to solve problems that may be modelled as the direct or oblique impact of two smooth spheres, or the direct or oblique impact of a smooth sphere with a fixed surface.
