Question

A ball is travelling at a constant speed in one direction, so the acceleration is zero. Justify the statement.

Answer 1

Answer:

We know that,

acceleration(a) = final velocity (v) - initial velocity (u) / time taken

If the speed is constant means the final and initial velocity are equal means they cancel each other and there is zero on the numerator so acceleration (a) = 0
