What is meant by aerodynamic drag?
Drag is the aerodynamic force that opposes an aircraft’s motion through the air. If there is no fluid, there is no drag. Drag is generated by the difference in velocity between the solid object and the fluid. There must be motion between the object and the fluid. If there is no motion, there is no drag.
What happens to the drag force on sphere with increasing radius size?
Explanation: See, by Stokes’ law drag is directly proportional to radius. As radius goes on increasing drag force must also be increased. Hope it helped.
How is aerodynamic drag measured?
The drag equation states that drag D is equal to the drag coefficient Cd times the density r times half of the velocity V squared times the reference area A. The drag depends directly on the size of the body. Since we are dealing with aerodynamic forces, the dependence can be characterized by some area.
Does drag force depend on mass?
Properties of the Air Drag depends directly on the mass of the flow going past the aircraft. The drag also depends in a complex way on two other properties of the air: its viscosity and its compressibility.
What is drag force at terminal velocity?
At terminal velocity, Fnet=0. Thus, the drag force on the skydiver must equal the force of gravity (the person’s weight). Using the equation of drag force, we find mg=12ρCAv2.
What is drag LGBT?
The term “drag” refers to the performance of masculinity, femininity or other forms of gender expression. A drag queen is someone (usually male) who performs femininity and a drag king is someone (usually female) who performs masculinity.
Is water resistance a push or pull force?
A force that tries to slow things down that are moving through air. It is a type of friction. Air resistance and water resistance are both sometimes called drag. A push or a pull….Forces.
| Word | Pronunciation | Meaning |
|---|---|---|
| lubricant | loo-brick-ant | A substance (normally a liquid) used to reduce friction. |
What are 4 types of forces?
Fundamental force, also called fundamental interaction, in physics, any of the four basic forces—gravitational, electromagnetic, strong, and weak—that govern how objects or particles interact and how certain particles decay.
Is friction a push or pull force?
When two surfaces slide over one another the tiny bumps push on each other. Friction causes a force on a surface which is in the opposite direction to its motion. Friction can be reduced by the application of lubricants.
