Question

If the velocity of an object changes from an initial value u to the final value v in time t,

the acceleration a is, a= (v – u )/ t. This kind of motion is known as accelerated motion. The

acceleration is taken to be positive if it is in the direction of velocity and negative when it is

opposite to the direction of velocity. The SI unit of acceleration is m s–2 .If an object travels in a

straight line and its velocity increases or decreases by equal amounts in equal intervals of

time, then the acceleration of the object is said to be uniform. The motion of a freely falling

body is an example of uniformly accelerated motion. On the other hand, an object can travel

with non- uniform acceleration if its velocity changes at a non-uniform rate. For example, if a

car travelling along a straight road increases its speed by unequal amounts in equal intervals

of time, then the car is said to be moving with non-uniform acceleration.
