If the velocity of a particle is nonzero, can the particle’s acceleration be zero? Explain.
Acceleration is the rate of change of velocity. A particle moving with constant velocity has zero acceleration.
If the velocity over a certain time interval is constant, the change in velocity is zero over this interval. Acceleration is the change in velocity with time. Therefore, the acceleration is zero.
If the particle moves with a constant non-zero velocity, the acceleration will be zero. Thus, the particle’s acceleration can be zero if the velocity of the particle is non-zero.
Conclusion:
Yes, the acceleration of the particle can be zero if the velocity of a particle is non-zero.
