Topic #8: X and Y COMPONENTS of VECTORS
... Often the value of a vector, its magnitude and direction, is known or given in a problem, but the question is to find the X and Y components of the vector. This is the opposite process from finding a resultant vector. The Mathematical Solution Method: Make a vector triangle, and use the sine and cos ...

Newton`s laws, part 1(Sep 20)
... Forces are important since they are the starting point of Newtonian mechanics. The idea is to analyze each body in a problem in isolation to determine the forces that act on it. If we know the initial position and velocity of the body, we then solve Newton’s equations of motion, to find out where th ...

Central Force Model

This is the centripetal force requirement. The word centripetal is merely an adjective used to describe th ...
