Question:
(a) Why does the tension force in the string not do work on the pendulum?
(b) Explain, however, why the force due to gravity on the pendulum at nearly every point does do work on the pendulum.
(c) Where is the single position of the pendulum where no work by gravity occurs?

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
