how do kenetic and potential energy effect a basic pendulum? How does gravity effect it?

Since this is not my area of expertise, I searched Google under the key words "pendulum kinetic potential energy gravity" to get these possible sources:

I hope this helps. Thanks for asking.

In a basic pendulum, kinetic and potential energy play a significant role in its motion.

The pendulum consists of a mass (bob) attached to a string or rod, which is usually fixed at one end. When the bob is at its highest point, it has the maximum potential energy, which is the energy stored in an object due to its position or state. As the bob swings down, potential energy decreases, while kinetic energy increases. Kinetic energy is the energy an object possesses due to its motion. At the lowest point of the swing, the bob has the maximum kinetic energy and minimum potential energy.

The interplay between potential and kinetic energy continues as the pendulum swings back up. As the bob moves higher, kinetic energy decreases while potential energy increases until it reaches its highest point once again. This energy exchange between potential and kinetic energy continues as long as the pendulum keeps swinging.

Gravity also plays a crucial role in the motion of a pendulum. Gravity is a force that pulls all objects towards the center of the Earth. It acts on the mass of the pendulum bob, causing it to accelerate towards the center of the Earth. As the bob swings downward, gravity accelerates it, increasing its kinetic energy. As the bob moves back up, gravity decelerates it, converting its kinetic energy back into potential energy.

In summary, the pendulum's motion involves a continuous exchange of potential energy and kinetic energy. Gravity acts on the mass of the bob, causing it to accelerate and decelerate, thus influencing the pendulum's motion.
