Momentum is the product of an object's mass and velocity.
A way to put momentum is that a player who is heavier and running very fast has a greater momentum than a player who is lighter and running at a slower speed.
Momentum is specific to something that is moving which makes sense via the equation
What is the conservation of momentum?
That in a closed system the total momentum before an event (e.g collision) is the same after the event
What is a closed system in physics?
Neither matter nor energy can leave therefore mass and energy stay constant
Changes in momentum?
A force causes the momentum to change. A bigger force makes it change faster.
