Momentum is a measure of how much mass an object has and how fast it is moving. It is calculated by multiplying the mass of the object by its velocity.
- Momentum is a vector quantity, which means that it has both magnitude and direction.
 - Momentum = mass x velocity.
 - Momentum is conserved, which means that the total momentum of a system remains constant unless an external force acts on the system.
 - Momentum can only be transferred between objects, not created or destroyed.
 - Examples of momentum:
- A bowling ball has more momentum than a baseball because it has more mass.
 - A car moving at 60 mph has more momentum than a car moving at 30 mph.
 - A rocket launching into space has a lot of momentum because it has a lot of mass and it is moving very fast.
