Question

what is the acceleration of a body moving with uniform velocity

Answer 1

If a body is moving with uniform velocity, acceleration is zero. So net force acting on it will be also zero. But the body has energy due to its constant motion.

Answer 2

The acceleration of a body moving with uniform velocity will be zero.

Solution:

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 formula,

$\bold{a=\frac{d v}{d t}=0}$

Thus the acceleration of the body will also be zero. As the final and initial velocity have same magnitude the acceleration will be zero.
