Question

A body moving with a uniform velocity of 20m/s. After 10 second what it's velocity will be ?

Answer 1

Answer:

since the body is moving in uniform velocity,

so the velocity after 10 second should be also 20 m/ s.

Answer 2

Answer:

It remains the same, ie; 20m/s.

Explanation:

If a body is moving with a uniform velocity, no acceleration acts on it. Acceleration is defined as the rate of change of velocity. If the acceleration is 0 (ZERO), then the rate would also be 0 (ZERO). If the rate is 0 (ZERO), the velocity won't change. So, be it 10 seconds or a 1000, velocity would remain the same (20m/s)...
