Newton’s Laws and Momentum — Interactive Lesson (Ages 14–16)

Why do passengers lurch forward when a bus brakes suddenly? Newton's laws explain how forces change motion. This 22-slide interactive lesson on Newton's laws takes pupils from first ideas to exam-style explanations, with 13 self-marking activities and nothing to prepare beforehand.

Teaching Newton's Laws and Momentum in GCSE Physics

Pupils calculate resultant forces, use Newton's first law to explain balanced forces and inertia, and use F = m × a and W = m × g in calculations. They identify third-law force pairs, calculate momentum with p = m × v, apply conservation of momentum to a collision and explain how seatbelts, airbags and helmets reduce the force on the body.

What Pupils Will Learn

• Calculate the resultant force on an object.
• 1⃣ Use Newton's first law to explain balanced forces and inertia.
• 2⃣ Use F = m × a and W = m × g in calculations.
• 3⃣ Identify Newton's third law force pairs.
• Calculate momentum and use conservation of momentum.
