Question

A particle revolves around a circular path then the acceleration of a particle is

Answer 1

Answer:

When particle move with constant angular velocity, it's linear velocity is obtained by drawing tangent at that point. We see that direction of tangent changes at every other point I.e. velocity changes at every point on circle. Velocity is vector, change in velocity per time is acceleration.

Hence though particle is in uniform circular motion, it has acceleration directed towards center along radius. This acceleration is centripetal acceleration or radial acceleration.

Another acceleration of particle is tangential acceleration or linear acceleration. When particle moves in circular motion, magnitude of tangential velocity remains the same though its direction changes continuously. Therefore tangential acceleration is zero in uniform circular motion.

If particle move with non uniform velocity then it has tangential as well as angular acceleration. Angular acceleration is change in angular velocity per time. In uniform circular motion angular acceleration is zero.

Hope this may help

Answer 2

Centripetal acceleration

Explanation:

When a particle revolves around a circular path then the acceleration required is centripetal acceleration.

It is directed radially  towards the center of circle.

Formula of centripetal acceleration

$a_c=\frac{v^2}{r}$

Where

v=Linear velocity of particle

r=Radius of circular path

By using the formula we can calculate the centripetal acceleration.
