Four forces are

• Weight
• Drag
• Thrust
• Lift

Weight is the force can bring the rocket down

Drag is the force that point to the ground,and the thrust is the reaction of drag,so thrust can make the rocket up.

Lift is produced by Bernooll’s principle–the pressure.

Here is the picture that shows these four forces

Bernooll’s principle is Faster velocity ,higher pressure
Slower velocity,lower pressure.The pressure difference between top and below give wing a lift,the length on top of is more longer then the below.The velocity on th top is faster then below,so the pressure on the below is higher then top,so air give wing a lift.
