The tangential and radial acceleration of a particle are a(t) and a(r) respectively. The motion of a particle is circular if

What is tangential and radial acceleration ?

Radial and Tangential Acceleration

During a accelerated motion of a particle

In circular motion of a particle,

In uniform circular motion of a particle

In a circular motion of a particle , the tangential acceleration of the particle is given by a_t = 9 m s^(-2) . The radius of the circle is 4m . The particle was initially at rest. Time after which total acceleration of the particle makes an angle of 45^@ with the radial acceleration is

A particle is moving on a circle of radius R such that at every instant the tangential and radial accelerations are equal in magnitude. If the velocity of the particle be v_(0) at t=0 , the time for the completion of the half of the first revolution will be

The average acceleration vector for a particle having a uniform circular motion is
