The Impulse of a Force - A Level Physics

This video introduces and explains the impulse of a force for A Level Physics.

When a force acts for a time it changes the momentum of an object. This is useful if you need to explain how an airbag in a car reduces the force on a person, or even how to get a straw through a potato!

The impulse of a force is defined as the product of a force and the time for which it acts.

Thanks for watching,
