Which force is the downward force due to gravity?

Which force is the downward force due to gravity?

• A. Lift
• B. Weight
• C. Drag
• D. Thrust

Answer: (B)

Weight is the downward force due to gravity acting on a mass. It equals mass times the acceleration due to gravity (about 9.81 m/s² on Earth) and points straight downward toward the center of the Earth. In drone flight, lift from the rotors must counteract this weight to hover or ascend. Lift is the upward force, thrust is the propeller-driven push that moves the craft, and drag is the resistance opposing the motion. So the downward gravitational pull is weight.
