If lift becomes less than weight, the plane.... | arrow_right_alt | ascends |
If lift becomes greater than weight, the plane... | arrow_right_alt | accellerates |
If thrust becomes less than drag, the plane.... | arrow_right_alt | decellerates |
If thrust becomes greater than drag, the plane... | arrow_right_alt | descends |
If lift, weight, thrust and drag become equal, the plane would..... | arrow_right_alt | hover |

|---|---|---|
The force that pulls objects down towards the ground. The more mass an object has, the greater the gravitational pull on the object. | arrow_right_alt | lift |
The force that gives an object a forward motion. The engines in an aircraft give it the thrust needed for flight. | arrow_right_alt | thrust |
The upward force that keeps a flying object in the air. Airplanes get lift from their wings. | arrow_right_alt | drag |
The force that acts to slow down an object as it moves through the air. Today, airplanes and other vehicles are often designed with smooth lines to cut through the air and overcome drag. | arrow_right_alt | gravity/weight |
