PHYSICS - Forces - Changes in Momentum

This video tutorial explains the concept of momentum, its calculation, and the dangers of rapid changes in momentum, such as in car crashes. It demonstrates how to calculate force from changes in momentum and discusses safety measures like seatbelts and airbags that reduce force by extending the time over which momentum changes occur.

What is the formula for calculating momentum?

Calculate the momentum of a 100 kilogram ostrich traveling at 8 meters per second.

Explain why rapid changes in momentum can be dangerous.

What is the change in momentum for an object that goes from 800 kilogram meters per second to 0?

How can seat belts reduce the force experienced by passengers during a crash?
