Question

What do you mean
by constant acceleration?

Answer 1

Definition: In case the velocity of a body increases or decreases by the same amount or magnitude of velocity in equal intervals of time and the direction of motion of the body does does not change, we say the body has constant acceleration. This case pertains to motion along a straight line.But when a body is moving in a horizontal circle with constant speed the body does have a constant acceleration equal to v²/r , where v is the constant speed in the circle and r is radius of the circle.

Answer 2

when an object changes its velocity at the same rate at equal intervals of time is called constant acceleration.
