A motion is said to be uniform, if a body
undergoes equal displacements in equal
intervals of time.
A motion is said to be non-uniform uniform, if
a body covers unequal distances in equal
intervals of time or if the direction of motion
Acceleration is defined as the rate of chang
velocity. Mathematically, we have a =
SI, it is measured in ms-2
The acceleration is said be positive, if it is in
direction of velocity and is negative, if
opposite to the direction of velocity.
