The string tension is greatest at the lowest point of the pendulum swing, where the mass is at its lowest position and experiences the highest acceleration. The tension is least at the highest point of the swing, where the string is almost vertical and the force of gravity is mostly perpendicular to the string.

Does the tension in the string of a swinging pendulum do any work?
No, the tension in the string of a swinging pendulum does not do any work. The tension force acts perpendicular to the direction of motion, so it does not apply a force in the direction of displacement. This means that no work is done by the tension force on the pendulum.
How many forces are acting on a simple pendulum?
At rest, tension in the string and weight of the bob are the two forces both equal and opposite. During its displaced position, the weight of the bod, tension of the string and restoring force all the three would act on it
What provides the centripetal force that keeps the motion of a pendulum oscillation?
The centripetal force that keeps a pendulum oscillating is provided by the tension in the string or rod to which the pendulum is attached. This tension constantly changes direction as the pendulum swings, always acting towards the center of the circular arc that the pendulum follows.
What forces and motion are in a pendulum swing?
The main forces at play in a pendulum swing are gravity and tension. Gravity pulls the pendulum bob downward while tension in the string keeps it swinging back and forth. The motion of the pendulum is an example of simple harmonic motion, where the pendulum swings back and forth with a constant period.
Define simple pendulum?
A simple pendulum is a mass (called the bob) attached to a string or rod of fixed length that swings back and forth under the force of gravity. The motion of a simple pendulum is periodic and follows the laws of simple harmonic motion. The period of the pendulum (time for one complete swing) depends on the length of the string and the acceleration due to gravity.
