# Does gravity cause a change in velocity? why?

Mar 16, 2018

Yes it does.

#### Explanation:

Gravity is applied to every single thing on Earth and changes from place to place, depending on the distance of a body to the center of the Earth.

A force applied to all bodies on Earth is Weight ($W$), which is caused by Earth's gravity.

If a body is free falling, its only acceleration is $g$, gravity. So gravity increases velocity. Without it, the said body would be still mid-air.

In case of flying or going upwards, weight decelerates a body, reducing its velocity.

If weight is stronger than the rest of the forces applied, then not only will velocity's meter change, but also its direction.
