What is the Acceleration of free fall?

The acceleration of free fall is the speed at which an object speeds up when falling freely under the influence of gravity alone. On Earth, this value is approximately 9.8 m/s². This means that if you drop an object from a height (and there is no air resistance), its speed increases by 9.8 meters per second every second it falls.

The acceleration of free fall is represented by the symbol g. It is nearly constant near the surface of the Earth but can vary slightly depending on location and altitude.

Here’s a simple example: If you drop a ball, after 1 second it is moving at 9.8 m/s, after 2 seconds it’s at 19.6 m/s, and so on, as long as no other force like air resistance slows it down.
