Detailed explanation-1: -Derivative of velocity with respect to time is acceleration. That means if accelerations is zero, velocity must be constant. Now that constant could be anything like it could be 5 m/s . Also if the velocity is 0(which is itself a constant) also indicates that acceleration is zero.
Detailed explanation-2: -Correct answer: If an object is moving with constant velocity, then its acceleration must be zero. We can then look at Newton’s second law. If the acceleration is zero, then the net force must also be zero.
Detailed explanation-3: -Acceleration is the rate of change of velocity of an object with respect to the time over which this change occurs. It is possible to have a non-zero value of acceleration when the velocity of a body is zero.
Detailed explanation-4: -Acceleration of an object can be zero when it is moving with a constant velocity. Since velocity is constant, there will be no change in velocity and so there will be no acceleration.
Detailed explanation-5: -At constant velocity acceleration is equal to zero. Slowing down is called negative acceleration or deceleration.
