Objects don't accelerate at a constant speed due to gravity. Instead, they accelerate at a constant *rate* due to gravity. This rate is called the acceleration due to gravity and is denoted by g.

Here's what you need to know:

* g is approximately 9.8 m/s² on Earth. This means that for every second an object falls, its downward velocity increases by 9.8 meters per second.

* g is not constant everywhere. It varies slightly depending on factors like altitude and the density of the Earth below you.

* g is independent of the object's mass. A feather and a bowling ball will fall at the same rate in a vacuum (ignoring air resistance).

Important Note: Air resistance plays a significant role in how fast objects actually fall. In reality, a feather will fall much slower than a bowling ball because air resistance affects it more.
