What do you mean by constant acceleration?

Constant acceleration means change in velocity per unit time should be constant. i.e.,



It means body should be changing its velocity with equal amount in equal time interval.

A body leaving a certain point “O” moves with a constant acceleration. At the end of the 5th second its velocity is 1.5 m/s. At the end of the sixth second the body stops and then begins to move backwards. Find the distance traversed by the body before it stops.

Determine the velocity with which the body returns to point “O“?

 16

Distinguish between speed and velocity.

 18

When the velocity is constant, can the average velocity over any time interval differ from instantaneous velocity at any instant? If so, give an example; if not explain why.

 19

Can the direction of velocity of an object reverse when it’s acceleration is constant? If so give an example; if not, explain why.
