    A pendulum swings due to the force of gravity acting on it. A pendulum consists of a weight (often called a bob) attached to a rod or string that is suspended from a fixed point. When the bob is displaced from its resting position and released, gravity pulls it downward, creating a restoring force that causes it to swing back and forth.

    The motion of a pendulum follows a regular pattern known as simple harmonic motion. As the bob swings to one side, it gains momentum and its potential energy is converted into kinetic energy. As it reaches the highest point on its swing, it momentarily stops and its kinetic energy is converted back into potential energy. This continuous exchange between potential and kinetic energy allows the pendulum to swing back and forth.

    The time it takes for a pendulum to complete one full swing is called its period, and it depends on the length of the pendulum and the acceleration due to gravity. The longer the pendulum, the slower it swings, and vice versa. The period of a pendulum can be calculated using the formula:

    T = 2π√(L/g)

    where T is the period, L is the length of the pendulum, and g is the acceleration due to gravity.

    Pendulums are used in various applications, such as timekeeping devices (e.g., grandfather clocks), scientific experiments, and even amusement park rides. Their regular and predictable motion makes them useful in these applications.
