what is difference between centripetal and centrifugal force?

A centripetal force is a force that makes a body follow a curved path. Its direction is always orthogonal to the velocity of the body and towards the fixed point of the instantaneous center of curvature of the path. The centripetal force is directed at right angles to the motion and also along the radius towards the centre of the circular path. Centrifugal force is the apparent force that draws a rotating body away from the center of rotation. It is caused by the inertia of the body The concept of centrifugal force is applied in rotating devices such as centrifuges,centrifugal pumps, centrifugal governors, centrifugal clutches, etc., as well as in centrifugal railways, planetary orbits, banked curves, etc. read less

Centrifugal force describes the tendency of an object to go a curved path outwards, away from the center . It's pseudo force resulting from inertia and resist any change in its state of rest or motion. Centripetal force is a real force that opposes the centrifugal force and does not allow object to go outwards, maintaining it moving with a uniform speed along a circular path. read less

Centripetal Force Consider a stone of mass m tied to thread if we whirl it we could see it moving in a circular path with a velocity assumed as v. So what keeps the stone move towards the centre? This is what we call Centripetal force. The Centripetal force is the force which keeps the body move along the axis of rotation and this force is acting always towards the center. The Centripetal force formula is given by Where m = mass of the moving body, V = Velocity with which it is moving, r = radius of circular path. The Centripetal force is due to the Centripetal acceleration and is given by Where ac is the Centripetal acceleration and is given by v 2 r . The Centripetal force is expressed in Kgm/s2 or N. Centrifugal Force/Accelaration The acceleration is the rate of change in the velocity of a moving body with respect to the given time. The acceleration can be classified according to the type of velocity and speed. If the body is in constant velocity then it is in the condition of constant acceleration because there is no change in velocity in the given time period. If a body is moved on circular path then it has a rotational acceleration due to rotational acceleration. Similarly, some other types of accelerations are centripetal and centrifugal acceleration. Here we are discussing about the centrifugal acceleration. The centrifugal acceleration is the acceleration that is on the curved path. When a car takes a U turn on the curved way then it does not fall towards the centre. This is due to the centrifugal acceleration which makes the motion of the car. read less

Centrifugal force (Latin for "center fleeing") describes the tendency of an object following a curved path to fly outwards, away from the center of the curve. It's not really a force; it results from inertia — the tendency of an object to resist any change in its state of rest or motion. Centripetal force is a real force that counteracts the centrifugal force and prevents the object from "flying out," keeping it moving instead with a uniform speed along a circular path. read less
