The force of lift is what makes airplanes fly. It results from an effect called the Bernoulli Effect when air passes over and airfoil, a surface which is curved on the top and flat on the bottom. The air passing over the upper surface has farther to go and therefore goes faster than that passing over the lower surface. The faster-moving air causes the pressure above the airfoil to reduce, causing the wing to rise.
What else can I help you with?
What is the greater mass of an object is the force of lift?
If the mass of an object is greater than the force of lift, the object will not be able to overcome gravity and will not be able to lift off the ground. It is important for the force of lift to be greater than or equal to the mass of the object for it to be able to achieve lift.
What kind of force does a porter apply to lift an object?
A porter applies an upward force called the lifting force to lift an object. This force must be larger than the weight of the object to overcome gravity and lift it.
When using a lever to lift a 45 N rock a force in or a force out?
When using a lever to lift a 45 N rock, the force required would be an input force. This is because you are applying the force to the lever to lift the rock against the force of gravity. The output force would be the force exerted by the lever on the rock.
What is force of lift and thrust?
Lift is the force that acts upwards, perpendicular to the chord of the wing. Thrust is the force acting perpendicular to the propeller disc.
What force gets a plane into the air is?
the force is lift
What is the lift force in an aircraft?
The lift force is the force acting against the aircraft's weight. For straight and level flight, lift acts in the upward vertical direction and the weight of the aircraft acts in the downward vertical direction. For level flight, lift = weight.
Upward force on a bird's wing?
It is called Lift. The difference in pressure above and below the wigs as a bird moves through the air produces an upward force that causes the bird to rise.
What force present of you lift a pencil off the top of a desk?
The force required to lift a pencil off a desk is the gravitational force acting on the pencil. When you lift the pencil, you are exerting an upward force that overcomes the force of gravity pulling the pencil downward.
What fluid opposes lift?
Parasitic drag is a fluid force that opposes lift. It is caused by the friction and resistance of the air against the surface of the aircraft, slowing it down and requiring more power to maintain lift.
Is the force that keeps an airplane in the air called lift or levitation?
Lift
Do the moveable pulley decreases the input force?
Do the moveable pulley decreases the input force?
When talking about flight what does lift mean?
Lift is the force caused by the wind under the wings. This force is what keeps the plane flying in the related links box below I posted the wikipedia lift force article for more details.
