Free fall is the type of motion of a body or an object when only gravity is acting on it.
<em><u>All objects undergo free fall on the earth surface at the same rate irrespective of their mass. This is because the gravitational field on the surface of the earth 9.8 N/kg, causes and acceleration equivalent to 9.8 m/s/s of any object in free fall motion.</u></em>
Therefore,<u> the acceleration of any freely falling object near the surface of the earth is 9.8 m/s².</u>
