About OCR A Level Physics A Newton’s Laws of Motion and Momentum

This topic covers momentum and its conservation.

What you need to know

  • Newton's laws First, second and third laws.
  • Momentum p = mv and conservation.
  • Impulse FΔt equals change in momentum; area under F-t graph.
  • Collisions Elastic and inelastic collisions.

Common mistakes in Newton’s Laws of Motion and Momentum

  • Mixing third law pairs.
  • Forgetting momentum direction.
  • Assuming energy is conserved in all collisions.

Try three Newton’s Laws of Motion and Momentum exam-style questions

1. State Newton's second law. (1 mark)

Show the mark scheme answer

Resultant force is proportional to the rate of change of momentum.

2. Find the impulse of a 10 N force for 0.50 s. (1 mark)

Show the mark scheme answer

5.0 N s.

3. Explain why crumple zones reduce injury. (2 marks)

Show the mark scheme answer

They increase collision time (1), so force is smaller for the same momentum change (1).

Newton’s Laws of Motion and Momentum FAQs

What does this topic cover?
