Question

When a particle is in uniform circular motion it does not have:
(A) Radial velocity and radial acceleration
(B) Radial velocity and tangential acceleration
(C) Tangential velocity and radial acceleration
(D) Tangential velocity and tangential acceleration

Answer 1

Hint : An object is said to be in motion when it is not at rest. An object is considered to be in motion, when it is continuously changing its position with respect to some steady and stationary reference point with respect to time. There are various types of motion.

Complete Step By Step Answer:
On every moving object or any particles, the physical quantity such as velocity and the acceleration affect the motion.
In the uniform circular motion, the tangential speed remains the constant and therefore the tangential acceleration is zero.
Also, since the radius of the circle remains the constant and hence, the radial velocity is zero.
The option B is the correct answer.

Note :
The radial velocity of an object can be defined as the rate of change of the distance between the object and the point of observation. The radial acceleration can be defined as the acceleration of the object which is long the radius which directs towards the centre. The tangential velocity can be defined as the linear speed of any object moving along the circular path whereas the tangential acceleration can be defined as change in the tangential velocity of the point with specific radius with the change in time in the circular path.
