Lift (force) - Wikipedia, the free encyclopedia

Lift, or downforce as its known in the motor racing world, is the force generated perpendicular to the direction of travel for an object moving through a fluid (gas or liquid). Assuming the flow is aligned with the z-direction, the total force is resolved into lift and drag force components as:

Lift is the force that holds an aircraft in the air. Lift can be generated by any part of the airplane, but most of the lift on an airplane is generated by the wings. Lift is a mechanical force. It is generated by the interaction and contact of a solid body with a fluid (liquid or gas).

The lift force, lifting force or simply lift is the sum of all the forces on a body that force him to move upwards (or to be exact for the case of negative lift: vertical). Specifically, the term negative lift means the lift force directed "down".

A force produced perpendicular to the flow of a fluid. It is predicted by Bernoulli's law for any obstacle which compresses streamlines at one boundary and compresses them on the opposite one, resulting in a difference in pressures which causes the lift force F_L ={{1\over 2}}C_L\rho v^2\alpha A, where C_L is the lift...

To overcome the weight force, airplanes generate an opposing force called lift. Lift is generated by the motion of the airplane through the air and is an aerodynamic force. "Aero" stands for the air, and "dynamic" denotes motion. As with weight, each part of the aircraft contributes to the aircraft lift force.

Those flying machines that don't utilize Bernoulli's principle for lift use buoyant force. Archimede's principle states that there is an upward force on an object in a fluid equal to the weight of the fluid it displaces.

A force acting on a body in a fluid in a direction perpendicular to fluid flow. Lift may assume any direction as determined by the direction of fluid flow and the orientation of the body; The lift force, lifting force or simply lift is a mechanical force generated by solid objects as they move through a fluid.[1]

The idea of Nolte was that the modern rowing style was based on the use of the lift force as the main propulsive force in rowing in the early phase of the pull. is the lift force, it carries the plane, and by definition it does not do work. F...
