Yesterday I learn what is the 4 types of forces are:

• Weight
• Lift
• Drag
• Thrust

Weigth  is  the force generated by gravitational attraction on the rocket. Lift is used to overcome the weight of the aircraft.

Lift is use to overcome the weigth of the aircraft.

Thrust is used in opposition to weigth.

Drag is a component of aerodynamic force ,namely the projection on the two direction parallel to the relative wind.
