Newton`s 2nd Law
... What does F =MA mean? Force is directly proportional to mass and acceleration. Imagine a ball of a certain mass moving at a certain acceleration. This ball has a certain force. Now imagine we make the ball twice as big (double the mass) but keep the acceleration constant. F = ma says that this new ...

Rotational Dynamics
... Center of Gravity In analyzing the equilibrium of an object, we see that where a force is applied to an object influences the torque produced by the force. In particular, we sometimes need to know the location at which an object’s weight force acts on it. Think of the object as a collection of smal ...
