Theory: The relationship between two physical quantities can be determined by graphical means. For a simple pendulum‚ the relationship between periodic time and length is given by the equation Where‚ T is the periodic time‚ 1 is the length of the pendulum string and g is acceleration due to gravity A graph of periodic time

Step 1: The hand holding the the weight in the pendulum will release the weight and allow it to swing forward to hit the car. This is potential energy by the force of motion of the weight on the pendulum. Potential energy is the energy an object produces due to its position. The pendulum swinging is it being in motion therefore it has kinetic energy. The force shown form this could be Applied Force. Applied force is a force that is applied to an object by a person or another object. Step 2: After
