The product of the mass of the object and its velocity
Momentum unit of measurement
mass velocity
Impulse
The product of force and the time it acts on an object
If there is a change in the velocity or the mass of an object, there is also a change in momentum. This change in momentum is called IMPULSE.
Impulse-Momentum Theorem
The impulse applied to an object is equal to the change in its momentum
The Impulse-Momentum Theorem is considered an alternative to Newton's 2nd Law of Motion that states the net external force acting on an object is responsible for the acceleration of the object
For an isolated system, the total momentum before interaction equals the total momentum after interaction
Collisions occur when two or more bodies come in contact with each other; they exert a force on each other
Linear momentum is always conserved in collisions
Momentum before collision = momentum after collision
