... The deriving force for the motion of the mass is mgSin(θ). For small angles this can be written as mgx/L which shows that the force is proportional to the horizontal position x. The acceleration, gx/L is also proportional to x. The graph of acceleration versus position in Fig. 4 shows this behaviour ...

An interaction that can cause an acceleration of a body is called a force. Force can be loosely defined as a push or pull on the body. The r ...
