👉 In physics, a pendulum is an oscillating device that consists of a bob or object attached to a string that swings back and forth. The motion of this device is influenced by gravity, and it can be used to measure forces and accelerations in various fields such as astronomy, geology, and engineering. A pendulum can have any number of nodes, which are points on the ends of the string where the bob's position changes. In a simple pendulum, there is only one node
