What is the difference between free fall and projectile motion?

Back

Free fall is only influenced by gravity, while projectile motion is influenced by both gravity and an initial velocity.

What happens to the acceleration of an object in free fall as it falls?

Back

It remains constant at 9.8 m/s².

Front

What is terminal velocity?

Back

The constant speed an object reaches when the force of gravity is balanced by air resistance.
