3.5 Newton's Laws and Momentum
3.5.1 Newton's Law of motion
Learners should be able to demonstrate and apply their knowledge and understanding of:
(a) Newton’s three laws of motion
Newton's First Law
Newton's Second Law
Newton's Third Law
General Newton's Laws
(b) linear momentum; p = mv; vector nature of momentum
(c) net force = rate of change of momentum; Learners are expected to know that F = ma is a special case of this equation.
(d) impulse of a force; impulse = F x t
(e) impulse is equal to the area under a force–time graph.
3.5.2 Collisions
Learners should be able to demonstrate and apply their knowledge and understanding of:
(a) the principle of conservation of momentum
(b) collisions and interaction of bodies in one dimension and in two dimensions Two-dimensional problems will only be assessed at A level.
Two dimensional collisions
(c) perfectly elastic collision and inelastic collision.
