### Lift Force and Drag Force | Symscape

Apr 04, 2007· Formula 1 racing cars corner at incredible speeds generating lateral forces up to 4.5 times that of gravity. Yachts can circumnavigate the globe by wind power alone. These incredible feats are all due to the lift force generated by airfoils moving through air. Of course nothing comes for free; for lift, the cost is drag.

### How much force is needed to raise an object from the ...

May 11, 2017· In layman's terms, any force greater than the object's weight will lift it from the ground. More mathematically, to accelerate an object upward requires a force of F=ma, where m is the mass (in, say, kilograms), a is the gravity on the earth's sur...

### Downforce - Formula 1 Dictionary

Cl is the coefficient of lift, again determined by the exact shape of the car and its angle of attack. In the case of a modern Formula 1 car, the lift-to-drag ratio Cl/Cd has a typical value of, say, 2.5, so downforce dominates performance.

### What is the lift formula or equation? - Helicopter Study Guide

Aug 16, 2018· The lift formula or equation is CL ½ p V2 S. This formula is used to quantify the factors or components that influence lift production. The factors are coefficient of lift, air density, velocity, and surface area. Not all factors of the equation are equal. CL is the coefficient of lift.
