Acceleration due to gravity is the acceleration caused when Earth pulls any object downward towards itself. Earth has a natural tendency to exert a force on any object because of which reason every time we jump up, we eventually fall down on the ground. Acceleration due to gravity calculator is the online tool which can be used to find the changes in an object due to gravity.

**Example 1: An object is thrown from the roof of a building. Find the time taken for it to reach the ground if it travels with a velocity of 80m/sec.**

Since here the object is pulled downwards only by the earth, hence acceleration acting is due to gravity denoted by ‘g’.

So 9.8 =

Time

Mass of the object = 50kg

where ‘W’ stands for weight, ‘m’ is the mass of the object

And ‘g’ is the acceleration due to gravity=9.8 m/sec

So, weight of the object = (mass of the person) * (g)

50kg * 9.8m/sec
