Correction to free fall

[matcbu]

Free fall can occur when something is moving upward.

In the following paragraph from the accelerometer page:

Accelerometers can also be used to detect when an object is in free fall, which is when only the force gravity is acting upon an object. If you were to throw a ball directly into the air, free fall would begin as soon as the ball begins its decent after the acceleration from your throw has subsided.

Change last sentence to:
If you were to throw a ball directly into the air, free fall would begin as soon as you let go of the ball.
