Question

Distinguish between centripetal and centrifugal force.

Answer 1

Difference between centripetal force and centrifugal force:

Centripetal force	Centrifugal force
1. The centripetal is defined as the force that acts on an object in a curvilinear motion and is defined as a component of the force directed towards the axis of rotation or the center of curvature.	1. Centrifugal force is defined as the force that results from the inertia of an object and appears to act on the moving object in a circular path directed away from the center in which it is moving.
2. Centripetal force is a real force.	2. It is a fictitious force.
3. Centripetal force is always radially inwards toward the center of the circular path.	3. The centrifugal force drives the object away from the center.
4. Example: The rotation of satellites around a planet.	4. Example: The sensation you have when riding a merry-go-round that makes you want to fly outwards.
