What is motion due to gravity?

 

MOTION DUE TO GRAVITY:

                                            Everyone has observed the effect of gravity as it causes objects to fall downward. In the absence of air resistance, it is found that all bodies at the same location above the earth fall vertically with the same acceleration. Furthermore, if the distance of the fall is small compared to the radius of the earth, the acceleration can be considered constant throughout its fall.

     The motion, in which air resistance is neglected and the acceleration is nearly constant, is known as free-fall.   

            The acceleration of a freely falling body is called acceleration due to gravity, and its magnitude (without any algebraic sign) is denoted by the symbol g.
