What is lift? With the help of an experiment, describe how it occurs
Answers
Step-by-step explanation:
Lift occurs when a moving flow of gas is turned by a solid object. The flow is turned in one direction, and the lift is generated in the opposite direction, according to Newton's Third Law of action and reaction. Because air is a gas and the molecules are free to move about, any solid surface can deflect a flow.
Answer:
Lift is the force that directly opposes the weight of an airplane and holds the airplane in the air. Lift is generated by every part of the airplane, but most of the lift on a normal airliner is generated by the wings. Lift is a mechanical aerodynamic force produced by the motion of the airplane through the air. Because lift is a force, it is a vector quantity, having both a magnitude and a direction associated with it. Lift acts through the center of pressure of the object and is directed perpendicular to the flow direction. There are several factors which affect the magnitude of lift.
experiment
Next time when you will ride a car on a highway pull your hand out of the window .You will notice that if you will tilt your hand upward, your hand will get pushed up. That is Reaction lift, and it is exactly the same as this second source of aerodynamic lift for aircraft.
