The term centrifugal is derived from a Latin word which literally means centre fleeing. It means directed in an outward direction from the centre. Centrifugal force is defined as a force that acts on a body which is spinning upon an axis. This force is directed away from the body. Centrifugal force is equivalent but opposite to the centripetal force.
Centrifugal, in simple terms, means something that has a tendency to move away from the centre. Outward is defined as a force which is apparent and acts from the outward side on a body which is moving about on a centre. It is a movement or progressive development away from the centre.
The centrifugal force is exerted from a distance away from the centre of a circle. An apparent centrifugal force is exerted or incurred when the centripetal acceleration is ignored. It is a deliberate away movement from the centre or axis.
Force" is a push or a pull which changes the motion, or movement, of objects. When you push a chair, you are exerting force on it. When you stop pushing, the chair stops moving. But suppose you roll a ball along the ground. It keeps on rolling after you have stopped pushing it! Why?
The explanation for this (developed by Sir Isaac Newton, the first scientist to explain the theories of force) is the idea of "inertia". Inertia makes an object keep up whatever motion it has. Every bit of matter has inertia and will keep moving in a straight line at the same speed unless another force changes its motion. For example, if you are riding in a bus and the driver jams on the brakes, your body will hurl forward because of its inertia—it will keep on going forward at the same speed the bus was travelling.
Now let us get to centrifugal force. All of us have experienced this force. We notice it whenever an object travels in a curved path. Let us say you are on that same bus and it suddenly turns a corner. You will probably find yourself falling off the seat into the aisle! The reason is centrifugal force.
Centrifugal force can be explained by using the idea of inertia. When the bus turns, inertia tends to keep your body moving in a straight line. So you tend to move toward the outside of the curve so as to keep your original straight motion. Centrifugal force always seems to push objects to the outside of the curve.
This is why main roads are often tilted around a turn; why aeroplanes bank when they turn; and why, when you are riding a bicycle, you lean inward! This leaning inward, and the banking of roads and aeroplanes, helps to balance centrifugal force, which would otherwise tend to hurl objects outward. The leaning inward the tendency to move outward and you can make the turn properly.
The difference is due to difference in the Frame of Reference chosen to analyze the problem. Let's take the example of circular motion of a stone tied to the string being moved in a circle of a certain fixed radius. In the frame of reference of the ground, the stone is moving in a circular path i.e. There must be a force acting on the stone to continuously change it's path / direction of motion. This we can show to act towards the centre of the circle and hence the name Centripetal Force. In the frame of the stone or an observer sitting on the stone, the reference frame is a non-inertial one. Now in order to apply Newton's Laws the observer must use a Pseudo - force which in this case is the Centrifugal force. To find its direction the observer would think that for him to be at rest (all observers think so!!!) there must be a force that is balancing the tension in the string. As the tension always acts radially inwards, this balancing force will act radially outward at all times during the motion.
When any object travelling in circular manner then that object experience a out word force e.g. When a person sitting in a marry go round at that time when it start to rotate at that time, the person feels out word force and that force is called centrifugal force. And in a same manner another one force whaich is not allowing person to go out of circamferance i.e. Means the object is also having directed towords center of circle that is called centripetal force
Centrifugal force is the apparent force, equal and opposite to the centripetal force, drawing a rotating body away from the center of rotation, caused by the inertia of the body.
