Obviously so it can overcome gravity and take off.
An airplane needs enough lift to overcome its weight in order to fly. The amount of lift required depends on factors such as the aircraft's weight, velocity, wing design, and air density. Pilots can adjust the airplane's angle of attack and airspeed to generate the necessary lift for flight.
When weight is greater than lift, the airplane will begin to descend. This imbalance causes the airplane to lose altitude as gravity overcomes the lift force generated by the wings. To regain equilibrium, the pilot may need to adjust the angle of attack or power settings to increase lift.
There is a reason birds fly and pigs do not. Birds have hollow bones and are light. The lift of the wings can support their light weight. Pigs have heavy bones and do not have the strength to either jump or lift in their appendages to support their weight. In airplanes, a heavy airplane, C130, must have more lift in the wings than a light airplane.
No. They need air for lift.
Need Mike's weight to answer.
If you need to go a long ways, if you need to go fast, or if you need to carry a lot of weight.
Generates more lifting force
the difference between an helicopter creating lift and an airplane creating lift is simple. an airplane creates lift by moving forward and its wing that has an aerofoil shaped will create lift. this gives the lift for the airplane and to fly. for helicopters, instead of the aerofoil is fix like an airplane, the aerofoil wing is rotating and create lift. that is why the helicopter does not need to move forward to gain momentum to create lift. by rotating the aerofoil (the blade) the helicopter can creates enough lift to lift up the helicopter.and that's how it fly..
more carbohydrate on a runner - needs a lot of energy consumption. More protein diet on a weight lifter - need to build muscle to lift bigger weight.
Weight affects lift because as an object gets heavier, it requires more lift force to counteract gravity and stay airborne. This means that a heavier object will need more thrust or a larger wing surface area to generate enough lift to support its weight. Additionally, weight can impact the wing loading and stall speed of an aircraft.
Yes, you will need to lift it alot more often than a 10 kg or more weight tho
An aircraft needs an engine to get thrust and roll forward to gain lift.
