Momentum and Impulse
In this segment we define the terms momentum and impulse. We see the impulse-momentum theorem in action by analyzing the motion of a freerunner and the motion of an egg hitting two very different surfaces.

Learning Objectives
-Define key terms, including momentum and impulse.
-Explain that momentum is a vector quantity and the direction matters.
-Explain how an object’s change in momentum depends on the net force it experiences and the length of time the force is applied.
-Define impulse and how it relates to momentum through the impulse-momentum theorem.
-Discuss the real-life implications of manipulating variables within the impulse-momentum theorem.

Vocabulary
impulse (I) - the product of the force acting on an object over the time during which the force acts. impulse-momentum theorem - this theorem states that the impulse applied to an object is equal to the change in momentum of an object. momentum (p) - the quantity of motion of an object or, mass in motion; momentum is calculated by multiplying the mass of an object by the velocity of an object.
