when a body is moving with a uniform velocity, the acceleration is .............?
when a body is moving with a uniform velocity, the acceleration is also constant.
thats what i wrote for my physics test...but i think the answer is zero
sorry, i made mistake.
When a body is moving with constant velocity, that means there is no change in the magnitude of velocity. Since, acceleration is the rate of change of velocity so the answer is Zero.
A body moving with a uniform velocity does not at all have any acceleration because it has uniform velocity i.e acceleration of a body with uniform velocity is always 0.
oh...so constant is wrong?
@ShikhaDessai can i explain why acc. is zero
\[a=\frac{\Delta V}{\Delta T}\]Therefore, when velocity is constant, acceleration must be 0.
Acceleration is the rate of change of velocity. Since velocity is not changing, acceleration is 0.
velocity has both magnitude n direction. there is no change of magnitude n direction of uniform velocity. so acceleration is 0
if the magnitude of a velocity changes then the acceleration is not 0
if the direction of a velocity changes then acceleration is not 0
if both the magnitude n direction of velocity changes then acceleration is not 0
