What is lift force?
Q: What is lift force?
A: Lift force is the sum of all the forces on a body that force it to move perpendicular to the direction of flow.
Q: What is the most common type of lift?
A: The most common type of lift is that of a wing of an aircraft.
Q: What are some other common uses of lift?
A: Other common uses of lift include propellers on both aircraft and boats, rotors on helicopters, fan blades, sails on sailboats, and wind turbines.
Q: Can lift be in any direction?
A: Yes, lift can be in any direction. For instance, for a sail the lift is horizontal, and for the wing on a race car the lift is down.
Q: How is the production of lift explained?
A: The production of lift can be explained in a number of ways, but the simplest explanation is that the wing deflects air downward, and the reaction pushes the wing up.
Q: Are all explanations of lift production accurate?
A: No, not all explanations of lift production are accurate. Some have been shown to be false.
Q: What is the lift force's effect on a body's movement?
A: The lift force is what forces a body to move perpendicular to the direction of flow.
