Question

What is centripetal and centrif
ugal
acceleration & Give its expression
.​

Answer 1

centripetal acceleration is the acceleration which applied by a centripetal force,when an object move in cirlcular path.

For circular motion centripetal acceleration is must.

ITS EXPRESSION= V^2/R

where V,=speed of object R=Radius of orbit..

Centrifugal acceleration is a acceleration due to a pseudo force which is opposite to centripetal force.

ITS DIRECTION IS OPPOSITE TO CENTRIPETAL ACCELERATION.

Answer 2

ANSWER:

centripetal force: is defined as ,the force that is necessary to keep an object moving in a curved path and that is directed inward toward the center of rotation.

centrifugal force: is defined as the apparent force that is felt by an object moving in a curved path that acts outwardly away from the center of rotation.

Explanation: rate of change of tangential  velocity is called as centripetal acceleration.

                  F=mv²

centripetal acceleration given by : ac=Fm

                                                        mv²=   r  

                                                                     m    

                                                         therefore,ac =   v²    

                                                                                     r
