Question

A particle is moving with a uniform velocity. what is its acceleration?

Answer 1

1. Velocity is defined as the rate at which displacement changes.
2. Uniform velocity describes a motion in which a body moves at a consistent speed.
3. Acceleration is the rate at which velocity changes with respect to time.
4. As a result, in the situation of constant velocity, the direction and magnitude are also constant. There isn't any speed.
5. $a=\frac{\left(v_2-v_1\right)}{\left(t_2-t_1\right)}$
6. Also $a=\frac{dv}{dt}$
7. $dv$ is the change in velocity.
8. $dt$ is the change in time.
9. So for a constant velocity, acceleration is zero.

Hence, for an object moving with a uniform velocity, its acceleration is zero
