## ShikhaDessai Group Title when a body is moving with a uniform velocity, the acceleration is .............? one year ago one year ago

1. mayankdevnani Group Title

when a body is moving with a uniform velocity, the acceleration is also constant.

2. mayankdevnani Group Title

thats what i wrote for my physics test...but i think the answer is zero

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.

6. mayankdevnani Group Title

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?

8. mayankdevnani Group Title

@ShikhaDessai can i explain why acc. is zero

9. Shane_B Group Title

$a=\frac{\Delta V}{\Delta T}$Therefore, when velocity is constant, acceleration must be 0.

10. mayankdevnani Group Title

right @Shane_B

11. mayankdevnani Group Title

Acceleration is the rate of change of velocity. Since velocity is not changing, acceleration is 0.

12. shamim Group Title

velocity has both magnitude n direction. there is no change of magnitude n direction of uniform velocity. so acceleration is 0

13. shamim Group Title

if the magnitude of a velocity changes then the acceleration is not 0

14. shamim Group Title

if the direction of a velocity changes then acceleration is not 0

15. shamim Group Title

if both the magnitude n direction of velocity changes then acceleration is not 0
