# What is the difference between constant and uniform acceleration ?

If a body has zero acceleration then it has constant velocity of for example 40 m/s but when a body has a constant acceleration of 2m/s^2 then it has a uniform velocity of 2,4,6,.....m/s for time 1,2,3,....s but when it has uniform acceleration of 2,4,6....m/s^2 then the velocity is non-uniform-2,8,18...m/s for time 1,2,3....s.Then kindly explain the exact difference briefly.

If you are in a basic physics class, then there is no difference between constant and uniform acceleration. More advanced classes might differentiate between the two.

"If a body has zero acceleration then it has constant velocity of for example 40 m/s"

True.

"but when a body has a constant acceleration of 2m/s^2 then it has a uniform velocity of 2,4,6,.....m/s"

True, but I'd ditch the word "uniform."

"but when it has uniform acceleration of 2,4,6....m/s^2 then the velocity is non-uniform-2,8,18...m/s for time 1,2,3....s."

Yes, BUT -- I don't recall EVER seeing a problem worded this way. Instead, it would read "with a (constant) jerk of 2 m/s²." That would give you a linear (but non-constant) acceleration curve and a parabolic velocity curve.

Hope this helps!

An object subjected to constant acceleration will see it's velocity increase in a linear (straight line) fashion. However, an object subjected to uniform (or linear acceleration) will see the velocity increase non linearly, in other words a curve similar to quadratic or one of the higher power terms. But remember, just like stocks and shares, acceleration can go down as well as up. The above describes increasing acceleration and not deceleration.

no, when a body has an acceleration, it does NOT have a constant or uniform velocity.

the rest of your question is pretty meaningless.
