Impulse is the product of the average force applied to an object and the time duration over which it is applied. It is also equal to the change in momentum of the object.
congrats on reading the definition of impulse. now let's actually learn it.
Momentum: A measure of motion of an object, defined as the product of its mass and velocity; represented by $p = mv$.
Force: An interaction that changes the motion of an object when unopposed; measured in Newtons (N).
Collision: An event where two or more bodies exert forces on each other for a relatively short time.
