Question

3. When the body is moving with constant velocity, its acceleration is a. positive b. negative. c. zero. d. none of these​

Answer 1

Zero.

Acceleration is defined as the rate of change in velocity with respect to time.

That is, a = ∆v/∆t

If the velocity is constant, that is, it is not changing, then

∆v = 0

Substitute it in the formula for acceleration and we get acceleration zero.

Answer 2

Answer:

☆If a body is moving with a constant velocity, its velocity must be zero .

☆1)zero is the correct answer for your question..

Explanation:

●The rate of change of velocity is called acceleration.

Its unit is m/s^2 .

●Acceleration formula=

a= vf-vi

t.

☆●If the body is moving with constant speed means the velocity of tge body will not change the time.

The change of velocity is zero

acceleration =0/t=0..
