Question

For a plane to fly the thrust from the propeller has to be _____ the drag caused by fiction.

Answer 1

Greater than

Step-by-step explanation

When an airplane is in motion, there are four forces that act on it: lift and weight - which are vertical forces - and thrust and drag - which are horizontal forces.

For an airplane to fly, the force propelling it forward must be greater than the repulsive force acting on it.

Thrust is the force that propels the plane in the direction of motion while drag is the force that acts opposite to the direction of motion.

This implies that the thrust from the propeller must be greater than the drag.
