Question

what is acceleration due to gravity. derive it's formula

Answer 1

Any object placed in the field of the gravitational pull of the Earth experiences the gravitational force. Acceleration due to gravity is defined as the acceleration gained by an object because of the force of gravity acting on it. It is represented by 'g' and is measured in terms of m/s2.

the acceleration due to gravity on the surface of the Earth. The mass of the Earth is 5.979 * 10^24 kg and the average radius of the Earth is 6.376 * 10^6 m. Plugging that into the formula, we end up with 9.8 m/s^2.

Hi Dear 《¤_¤》,

☆Acceleration Due To Gravity :

》The acceleration produced in a body when it falls under the effect of gravity alone is called acceleration due to gravity.

》 It is denoted by the symbol 'g' and value on or near the surface of the Earth is 9.8 m/s^{2}.

☆Expression For Acceleration Due to Gravity :

Consider Earth to be a sphere of mass M and radius R. Suppose a body of mass m is placed on the surface of the earth, assume that distance between M and m is equal radius R, of the earth.

According to the law of gravitation ,

F = ( GMm ) / R^{2}

The attractive force which the earth except on the object is weight ( mg )
Then F = mg

mg = ( GMm ) / R^{2}

g = GM / R^{2}

》'g' does not depend on the mass of the body placed on the surface of the earth .

》G and M R constant. R does not change but has small variation.
