1. Linear Momentum
Linear Momentum is defined as 'the product of an objects mass and velocity'. That's straightforward but why does momentum have the symbol 'p'? This video starts with the basics before we look at conservation of linear momentum in the next video.

2. Conservation of Momentum
How quickly does a pistol recoil when you fire it? You can calculate an answer by considering the conservation of momentum for a closed system.

3. Impulse of a Force
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.
