What is a centrifugal force?

Centrifugal force is an inertial force that appears to act on objects that are moving in a circular path. It is a type of pseud-oforce that is often described as the force that pushes objects outward from the center of a circle when they are in circular motion.
To understand why this force appears to exist, it's helpful to consider an object that is moving in a circular path. When an object is moving in a circular path, it is constantly changing direction, and this change in direction is due to a force acting on the object. In the case of an object moving in a circular path, this force is called the centripetal force. The centripetal force is what keeps the object moving in a circular path and is directed towards the center of the circle.
When an object is moving in a circular path, it is constantly accelerating towards the center of the circle. This acceleration is necessary to keep the object moving in a circular path and is what causes the centripetal force. However, from the perspective of an observer standing on the object, it can feel like there is a force pushing them outward from the center of the circle. This force is the centrifugal force, and it appears to act in the opposite direction of the centripetal force.
It's important to note that the centrifugal force is not a real force, but rather it is a psychological effect that is due to the acceleration of the object. Despite this, the centrifugal force is a useful concept in physics and is often used to explain the behavior of objects moving in circular paths.
