Can a particle with zero acceleration speed up?

Open in App

Solution

If the body slows down, it should have negative acceleration.
When acceleration is zero, the object's speed may also be constant or zero.
The body controls its speed throughout the entire time. For example, if a train is at rest, its velocity and acceleration both stay zero.
However, when a train travels at a constant speed, the acceleration is zero and the velocity stays constant.
Because acceleration equals the change in velocity per unit of time, a particle cannot accelerate at zero acceleration.
As a result, the particle cannot increase speed without changing its velocity.
Therefore, no, since if the body speeds up, it should have a positive acceleration.

Q. If a particle is accelerating, it is either speeding up or speeding down. Do you agree with this statement?

Q. The velocity of a particle is zero at t = 0.
(a) The acceleration at t = 0 must be zero.
(b) The acceleration at t = 0 may be zero.
(c) If the acceleration is zero from t = 0 to t = 10 s, the speed is also zero in this interval.
(d) If the speed is zero from t = 0 to t = 10 s the acceleration is also zero in this interval.

A particle with one dimensional motion with positive value of acceleration must be speeding up.
