Question

an object is moving with constant velocity then find its acceleration

Answer 1

#AlexaRousey here!!

If a body is moving with constant velocity, velocity is always same.

Hence u = v (fr anytime in inertial Frame of reference)

Acceleration is a rate of change of velocity.

Since acceleration = v-u /t

= 0/t
= 0.

Thanks!!

Answer 2

Answer:

An object is moving with constant velocity then its acceleration will be equal to zero.

Explanation:

• We know that velocity is rate of change of displacement of a body in per unit time. It is a vector quantity which has magnitude as well as direction.
• Acceleration is the rate of change of velocity per unit time. It is given by:

        $a=\frac{v_2-v_1}{t_2-t_1}$

      Where v₂ is final velocity at time t₂ and v₁ is initial velocity of an object at time t₁.

• If their is any change in the path then the direction of an object will change and  the velocity will also change.
• If the change in velocity then acceleration changes as well.

Since the object is moving with constant velocity then  v₁ = v₂

∴  $a=0$

Therefore, acceleration of the body moving with constant velocity will be equal to zero.
