## ShikhaDessai 2 years ago when a body is moving with a uniform velocity, the acceleration is .............?

1. mayankdevnani

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

2. mayankdevnani

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

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

@ShikhaDessai can i explain why acc. is zero

9. Shane_B

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

10. mayankdevnani

right @Shane_B

11. mayankdevnani

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

12. shamim

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

13. shamim

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

14. shamim

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

15. shamim

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

thank u

u r most welcome
