Another incredibly useful topic (much like energy) is the concept of momentum. Momentum is another one of those mechanics subjects that you will use if you continue into more advanced physics (for example, sub-atomic particle physics). For now, momentum will serve the purpose of being the change in movement between two objects. Likewise, a change in momentum is called an impulse. As with all physics topics, its important to bear in mind how different topics (force, energy, power, etc.) relate to the topic at hand. In the video, youll see the basic equation for momentum, but also how it relates to integrating force.
Momentum (p) is a vector describing how difficult it is to stop a moving object.
The total momentum of a system is the sum of the individual momenta of the particles comprising the system.
Units of momentum are kg*m/s, or N*s.
A change in momentum is known as an impulse (J).
Impulse is change in momentum, as well as the product of the average force and the time it is applied.
The area under a force-time graph is the impulse applied to an object.
