**Motion of Objects Under the Influence of Gravitational Force of the Earth**

Let an object is falling towards earth with initial velocity *u*. Let its velocity, under the effect of gravitational acceleration *g*, changes to *v* after covering the height *h* in time *t*.

Then the three equations of motion can be represented as:

Velocity (*v*) after *t *seconds, *v *= *u *+ *ght*

Height covered in *t *seconds, *h *= *ut* + ½*gt ^{2}*

Relation between

*v*and

*u*excluding

*t*,

*v*=

^{2}*u*+ 2

^{2}*gh*

The value of

*g*is taken as positive in case of the object is moving towards earth and taken as negative in case of the object is thrown in opposite direction of the earth.
