Question

When an object is moving is constant velocity then its acceleration is zero

Answer 1

Answer:

Yes if an object is moving with constant velocity it's acceleration will be equal to 0

let us understand this by taking initial velocity as u and final velocity as v

v =u as the object is moving with constant velocity

first equation of motion = v=u+at

If a will be 0 V will automatically become equal to u

Answer 2

Answer:

Yup, this statement is right.

That,           velocity is constant or;

                                    initial velocity or u = final velocity or v ;

Then,               acceleration or a = 0;

Explanation: We know that acceleration is the rate of change of speed which can be written mathematically as;

                      a = $\frac{ v - u}{t}$                    (i)

here, v =final velocity;

         u = initial velocity;

          t = time taken;

Since, velocity is constant, hence;

                                 v = u;

Now, put the value in equation (i);

                      a = $\frac{ v - v}{t}$ or  $\frac{ u - u}{t}$   ;

                      a = 0 / t;

                      a = 0;

That's all.
