Lift: is also known as the upwards force. It helps to keep an airplane, aircraft, hovercraft, bird, etc. in the air by pushing it upwards. The wings of a bird or airplane are huge factors in how great the force of lift is. This is because the top of the wing is curved and the bottom is flat. When the air is traveling on top of the wing it goes faster creating a low pressure. When the air passes under the wing, it goes slower creating a high pressure thus pushing the object upwards.

What is an upward force?
It is a force which acts in the upward direction.
What force is needed to accelerate an elevator with a mass of 1000 kg upward at a rate of 2 m per second squared?
Weight of the elevator = 1000kg x -9.8m/s2 = -9800N Upward force acting on the elevator = 1000kg x 2m/s2 = 2000N Net force = upward force - weight of elevator = 2000N - (-9800N) = 11800N
How to convert Normal Force lbf to Lift lbf?
Lift lbf = (Normal force lbf) x (cosine of angle of attack)
What statement about airplane and rocket is true?
Only one requires air molecules to generate lift.
What is the force that enables planes to stay in the air?
Lift
