what is difference between centripetal and centrifugal force?
Answers
a force, arising from the body's inertia, which appears to act on a body moving in a circular path and is directed away from the centre around which the body is moving.
Answer:
Centripetal force
Centripetal force is the component of force acting on an object in curvilinear motion which is directed toward the axis of rotation or centre of curvature.
A few examples of Centripetal Force
1. Spinning a ball on a string or twirling a lasso: Here the centripetal force is provided by the force of tension on the rope pulls the object in toward the centre.
2. Turning a car: Here the centripetal force is provided by the frictional force between the ground and the wheels.
3. Going through a loop on a roller coaster: The force is provided by the Normal Force as the seat or wall pushes you toward the centre.
4. Planets orbiting around the Sun: Centripetal Force is provided by Gravity.
Centrifugal force
Centrifugal force is a force that arises from the body’s inertia and appears to act on a body that is moving in a circular path which is directed away from the centre around which the body is moving.
Centrifugal Force Examples in Daily Life
Centrifugal Force acts on every object moving in a circular path when viewed from a rotating frame of reference. Some examples of Centrifugal Force are given below.
1. Weight of an object at the poles and on the equator
2. A bike making a turn.
3. Vehicle driving around a curve
4. Equatorial railway
