GCSE Physics - Momentum Part 2 of 2 - Changes in Momentum #60

The video tutorial explains how forces can change an object's momentum, using the formula that relates force to the change in momentum over time. It provides examples of calculating force required to change momentum and discusses the importance of momentum in car crashes, highlighting safety features like crumple zones, seatbelts, and airbags that help reduce injury by extending the time over which momentum changes.

Why is it important to spread the change in momentum over a longer period of time during a collision?

Explain how crumple zones in cars function to enhance passenger safety.

Describe the role of seatbelts in reducing injury during a car crash.
