Momentum and Impulse: Understanding Forces, Motion, and Energy Conservation
This PowerPoint covers the concept of momentum, which is defined as the product of an object′s mass and velocity (p = mv). Newton′s second and third laws are applied to momentum, showing how momentum is conserved in interactions. The principle of impulse, where a large force acting over a short time changes momentum, is also discussed. The presentation explains the center of mass, how it is calculated, and its role in the motion of objects. The total momentum of a system is conserved unless acted upon by external forces, and the center of mass moves as if all mass were concentrated at that point.
