How do you calculate the speed of a falling object?

As an object falls, its speed increases because it's being pulled on by gravity. The acceleration of gravity near the earth is g = - 9.81 m/s^2. To find out something's speed (or velocity) after a certain amount of time, you just multiply the acceleration of gravity by the amount of time since it was let go of
