We just learned about the Air Resistance, part of ballistics which is the science of the forces that move a rocket around.

Another part of ballistics is Lift, which is all about how the air flows underneath a rocket that helps it fly up.

You can feel lift if there is a strong wind and you put your hand out flat, the air will try to push your hand up like a kite.
The way you hold your hand changes how the wind pushes on you, and rockets can use small fins or wings to try and use lift to help them fly.
