Momentum and Collisions - Mission MC2 Detailed Help

An impulse occurs when a ____ is acting upon an object for a given amount of ____ in order to cause a change in ____.

 
Definition of Impulse:
An object that encounters a collision will experience a force acting for a given amount of time to change its momentum. The impulse experienced by the object is the mathematical product of the force and time.


 
Meaning of Impulse:
When a force is exerted upon an object (whether in a collision or in any other situation), the object is said to have encountered an impulse. The impulse is simply the product of the force exerted on the object multiplied by the time over which the force was experienced. The impulse changes the object's momentum.
