Earth's gravity acts upon objects with steady force of 9.8 meter per second squared. Gravity is the attraction of earth acts on a body, that pulls it toward earth. The value of gravity is constant and equals to 9.8 m/s². The force of attraction can be calculated by:
F = ma
where, m is the mass and a is the acceleration due to gravity which is equals to g. The force of gravity is equals to the weight of the body and can be written as:
