Question

If a particle speed constant.the acceleration of a particle must be zero

Answer 1

Answer:

follow me

Explanation:

If speed is constant, particle may still have an acceleration. e.g. in uniform circular motion, speed is constant but as the direction of motion changes continuously, velocity changes and there is acceleration. hope this work

Answer 2

Answer:

yes the accelaration must be zero....

Explanation:

as we know that ,

a = dv/dt

if a is zero then,

a = 0

this means , v should be constant here as derivative of constant function is zero.....
