Question

a body is moving at 20 km per hour in a circular path.is the moving with uniform velocity.why/why not​

Answer 1

Explanation:

What is the velocity of your body moving with uniform?

The 'acceleration of a body' moving with uniform velocity will be zero as acceleration is defined as the “rate of change of velocity” per unit time. So if the body exhibit uniform velocity, then the rate of 'change of velocity' (dv = 0) will be zero. Thus the acceleration of the body will also be zero.

Answer 2

Answer:

The body is not moving at uniform velocity

Explanation:

why because a body is said to be moving with uniform velocity if it covers equal distance in a particular direction in equal intervals of time.

In case of circular path even if the body is moving with uniform speed is with variable velocity because the direction of motion of the body continuosly changes with time.
