What is drag force and what are its factors on which it depends?
Drag force is the resistance to motion of the object offered by the medium through which it travels, its value depends on the viscosity of the medium, and the shape, size and surface texture of the object. Note: for any given object, the drag force is equal to the square of the velocity * the drag coefficient of the object (rolling resistance is extra in the case of cars etc.)
How does the airfoil shape reduce drag?
Simply because it's the shape that can move through air causing the least amount of disturbances. Other shapes set off more small vortices which increase drag(= making it harder to push the item through the air) than the airfoil shape does.
What is an example of drag force?
A drag force is a dissipative force. This can be in the form of air resistance or fluid resistance. Drag force is a force that acts opposite to the relative motion of an object moving in a surrounding fluid.
How do thrust and drag relate?
Thrust is the FORCE that is trying to propel an object into Motion. Generally it is related to Jet or Rocket engines, but can be a measure of a propeller as well. Drag is the Force generated on the object by the Fluid that it is moving through, such as Water or Air. It is usually in direct relation to the shape of the object.
What force opposes motion through a fluid?
The force that opposed motion through a fluid is drag.
What is drag on a plane?
drag is minimized by aerofoil shape. drag is a force acts on aircraft to minimize speed
The SI unit of the drag force?
If you consider drag as a force, that would be Newtons.If you consider drag as a force, that would be Newtons.If you consider drag as a force, that would be Newtons.If you consider drag as a force, that would be Newtons.

How does the shape of a car make it faster?
the shape of the car is vital when designing because if you want a high speed car then it has to be aerodynamic this makes it easier for the air to go around the car and stops it from having drag drag is the force of the air that is pushing on a car if you want a fast car you need less drag
Does the size and shape of an animal affects the rate of motion Does the size and shape of an animal affects the rate of motion?
for a given force, a better drag coefficient will yield a greater velocity
What is air resistance and does it differs going up and down the earth and is there any resistance of gravity?
There exists a resistance force or drag force when any object moves through air or any other fluid.This force acts in direction opposite to the direction of the motion. This drag force depends upon the shape of the object, speed, and fluid properties. The parachute slows downward motion by offering a significant drag force to a falling object or person.

Olympic runners wear spandex clothing to counteract the same force that also affects airplanes in flight. what force is it?
Drag- APEX :)
What does the force drag mean?
"Drag" is the name given to the force of air resistance, or friction in general.
What is the meaning of drag?
Drag is something that is force exerted. It is a force that is exerted in the opposite direction of movement.
What relationship is there between the shape of an object and drag that is created?
Drag is due to the concept of fluid drag due to viscosity. This drag force can be calculated from an extremely hard to solve differential equation, the Navier-Stokes equation. For a sphere the equation simplifies to drag force=6*pi*viscosity*radius of the sphere*velocity. For other shapes with less symmetry the navier-stokes equation is harder to simplify. For example- a cube traveling through the air no longer has laminar, streamline flow of air. This results in turbulence and drastically increases the drag force. Hope that helps.
