Acceleration
The rate at which velocity changes in relation to time is referred to as acceleration. The instantaneous acceleration is provided if v is the speed and t is the time as

a i n t = \frac{d v}{d t}

.If

v 1

is the initial velocity and

v 2

is the final velocity is a total time period

T

, then the average acceleration is given as

a a v g = \frac{v 2 - v 1}{T}

.Therefore, the unit of acceleration is

m / s^{2}

.Acceleration is a vector quantity because velocity is one as well. The amount of force applied by the body is determined by multiplying its mass by the acceleration it experiences. If

S

is the displacement of the body, the acceleration can also be expressed as,

a i n t = \frac{d v}{d t} = \frac{d}{d t} (\frac{d S}{d t}) = \frac{d^{2} S}{d t^{2}}

.Examples of Acceleration
For a body in a uniform circular motion, even though its speed remains constant, its direction is constantly changing. This causes a constant change in velocity that results in the generation of acceleration.For a body that starts to move, it increases its velocity from

v 1 = 0

, since it is initially at rest to a final velocity

v 2

. Hence it undergoes acceleration.Similarly, for a moving body that comes to rest, it decreases its velocity from

v 1

v 2 = 0

. Hence it undergoes a negative acceleration, retardation, or deceleration.A freely falling body is acted upon by acceleration that occurs due to the gravitation attractive force of the earth.
