CHAPTER 9- CONSERVATION of MOMENTUM DEFINITION of
... In physics we define force as the time rate of change of momentum. Momentum as force is a vector quantity. F = dP /dt where P = M V COLLISONS In a collision between objects the internal forces are equal and opposite thus balance. The net work performed is zero! Since F = M dV/dt = d/dt (MV) = 0 we s ...

The work-energy relation
... Note: The work done on a particle by the resultant force applied on it over a given interval of time will be equal to the change in kinetic energy of the particle. In other words, the kinetic energy of a particle is changed by an amount equal to the work which is done on the particle by the resultan ...

Now we are interested in looking at how those functions change when the particle undergoes an interaction. The general idea of a particle coming to an area where the potential is changing, interacting ...
