Define centrifugal force.Give any two examples.

Explanation

In the reference frame of a particle performing circular motion centrifugal force is defined as a fictitious radially outward force on the particle and is equal in magnitude to the particle's mass' times the centripetal acceleration of the reference frame, as measured from an inertial frame of reference.
Exampies : (1) A person in a merry-go-round experiences a radiallyoutward force.
(2) Passengers in a car taking a turn on a level roadexperience a force radially away from the centre of the circular road.
(3) Acoin on a rotating turntable flies off for some high enough angular speed ofthe turniable.
