Question

If an object moves with uniform velocity 5m/s alongx-axis for 10s,its acceleration is

Answer 1

Hey there!
We know that , Acceleration is the Change of rate of velocity with respect to time.

In the given , An object moves with uniform velocity. Uniform velocity means The velocity of body is unchanging with respect to magnitude and direction.

So, We can say that, The body has uniform .So, The velocity of the body is unchanging. Now,

Change in velocity = 0 .

Acceleration = Change in velocity / Time = 0 .

So, The body given in the question is having zero acceleration.

[ Extra information : A body can have zero acceleration even if the velocity is non zero because change in velocity may be zero.]

Answer 2

Acceleration: Acceleration is referred to as the rate of change of velocity.

But here,

The object moves with an uniform velocity.

Acceleration = ( Final velocity - Initial velocity ) / time  

Uniform velocity: The velocity remains constant and does not change. Here, Initial velocity is equal to the final velocity.

Uniform velocity = 5 m/s  

Here,

Initial velocity = 5 m / s

Final velocity = 5 m / s

Substituting,

Acceleration = ( 5 - 5 ) / 10  

Hence, Acceleration = 0
