# what is difference between acceleration and acceleration dye to gravity ? explain with example.

Dear Student,
Acceleration of a body is defined as the rate of change of its velocity with time.
i.e Acceleration = Change in velocity/Time taken for change

or,
a=(v-u)/t
v - Final velocity of the body.
u - initial velocity of the body.
SI unit is m/s2
Therefore, acceleration is the rate at which something speeds up or slows down.
Example:
Consider a body moving with a velocity of 10 m/s.After 5 seconds, it acquires a velocity of 60m/s.
Acceleration of the body  is,
$a=\frac{v-u}{t}=\frac{60-10}{5}=10m/{s}^{2}$

Earth attracts every body towards it's centre.Whenever an object free falls towards earth,it gains some velocity and during it's journey the speed can change. So there is an acceleration caused due to gravity.This is known as acceleration due to gravity. It is denoted by g .Thus,acceleration due to gravity is the acceleration set up in the body when it falls freely under the effect of gravity alone. Its value on the earth's surface is 9.8 m/s2.

When an object falls freely towards the surface of earth from a certain height, then its velocity changes. This change in velocity produces acceleration in the object which is known as acceleration due to gravity denoted by letter g. The value of acceleration due to gravity is g= 9.8 m/s2.

Dear friend,

Acceleration is the rate of change of velocity with respect to time. It denoted by a.
a=v-u/t
We know that earth attracts objects towards itself. Whenever a object free falls it gains some velocity and the change in velocity take place. Basically there is some acceleration caused due to gravity this is known as acceleration due to gravity. It is denoted by g. The acceleration due to gravity on this planet is 9.8 m/s^2.
