Vector: A vector is a quantity that has both magnitude and direction. Linear momentum is a vector quantity because it depends on both the mass (magnitude) and velocity (direction) of an object.
Impulse:Impulse refers to the change in momentum experienced by an object when acted upon by a force for a certain amount of time.
Conservation of Momentum: Conservation of momentum states that in an isolated system, the total momentum before an event or interaction is equal to the total momentum after the event or interaction.
