Final answer:
True. The four forces of flight are thrust, drag, lift, and weight.
Step-by-step explanation:
The statement is true.
Thrust, drag, lift, and weight are indeed the four forces of flight. Thrust is the force that propels an object forward, like the force created by a rocket engine. Drag is the force that opposes the motion of an object through a fluid, such as air resistance. Lift is the force that allows an object to overcome gravity and stay airborne, like the lift generated by the wings of an airplane. Weight, also known as gravitational force, is the force exerted by the mass of an object and pulls it towards the Earth.
These forces work together to enable flight by balancing each other out. For example, in order for an airplane to take off and stay in the air, the lift generated by the wings must be greater than the weight of the airplane. Similarly, to move forward, the thrust provided by the engines must be greater than the drag.
