Summary of Important Quantities, Equations and Concepts[edit]
Momentum: The momentum of an object is defined as its mass multiplied by its velocity. Momentum of a System: The total momentum of a system is the sum of the momenta of each of the objects in the system. Principle of Conservation of Linear Momentum:: `The total linear momentum of an isolated system is constant' or `In an isolated system the total momentum before a collision (or explosion) is equal to the total momentum after the collision (or explosion)'. Law of Momentum:: The applied resultant force acting on an object is equal to the rate of change of the object's momentum and this force is in the direction of the change in momentum. |
