The force that causes the periodic motion of a pendulum is gravity. When the pendulum is displaced from its resting position, gravity acts as a restoring force that pulls it back towards equilibrium, resulting in the swinging motion.

What type of motion does a pendulum have?

A pendulum exhibits simple harmonic motion, which is a type of periodic motion where the restoring force is directly proportional to the displacement from equilibrium. This causes the pendulum to oscillate back and forth in a regular pattern.


Why does a pendulum have periodic motion?

A pendulum has periodic motion because as it swings, the force of gravity acts as a restoring force that constantly pulls it back towards its equilibrium position. This causes the pendulum to oscillate back and forth in a predictable manner.


What force causes the pendulum to fall?

Gravity is the force that causes a pendulum to fall. As the pendulum swings back and forth, gravity is constantly pulling it downwards, causing it to accelerate towards the center of the Earth. This force generates the motion of the pendulum.


Which type of motion is exhibited by tortional pendulum?

A torsional pendulum exhibits rotational periodic motion. You can create one by hanging some weight from a cord, and then rotating the weight. The cord becomes twisted, generating a torsion force, that will cause the weight to rotate in the oppopsite direction. Thus, a periodic rotation movement is generated.


What causes the restoring force in a pendulum?

Gravity, At any instant time the restoring force is the component of gravity acting parallel to the direction of the motion.


What is a real world ex of a periodic motion?

A real-world example of periodic motion is the swinging of a pendulum, such as in a grandfather clock. The pendulum swings back and forth in a regular and repeating motion, controlled by the force of gravity.


What is the role of centripetal force in the motion of a pendulum?

The centripetal force in a pendulum is responsible for keeping the pendulum swinging in a circular motion. It acts towards the center of the circular path, allowing the pendulum to continuously swing back and forth.


Is a pendulum an unbalanced force?

a pendulum is not only an unbalanced force it also is a "swinger" that swings in a back and forth motion because of this "force"


What is mean position in pendulum?

The mean position of a pendulum is the equilibrium point where the pendulum comes to rest when not in motion. It is the point where the gravitational force acting on the pendulum is balanced by the restoring force.


More differences between simple harmonic motion and periodic motion with practical examples?

Simple harmonic motion is a type of periodic motion where the restoring force is directly proportional to the displacement from equilibrium. Practical examples include a swinging pendulum or a mass-spring system. Periodic motion, on the other hand, refers to any repeated motion that follows the same path at regular intervals, such as the motion of a wheel rotating. So, while all simple harmonic motion is periodic, not all periodic motion is necessarily simple harmonic.


What is an example of periodic motion?

An example of periodic motion is a swing moving back and forth. The swing repetitively oscillates around a fixed point due to the force of gravity and the initial push given to it. The motion of the swing follows a pattern that repeats at regular intervals.


What are the scientific concepts involved in the pendulum?

Rotation, harmonic motion, and force.
