Free fall and acceleration due to gravity ===
'''Free fall and acceleration due to gravity'''
A freely falling body undergoes acceleration. This acceleration is caused by the gravitational force exerted by the larger mass of the Earth. This is referred to as acceleration due to gravity. The Earth also undergoes an acceleration due to the gravitational force exerted by the object. We do not notice it because of the mass of the Earth. This is represented by "g" and has the value of 9.8 m/s2.
