What are the 2 things that most affect the amount of drag an object experiences?

To keep the topic simple, it can be said that the two most common factors that have a direct effect upon the amount of air resistance are the speed of the object and the cross-sectional area of the object.

Why does an object experience drag?

Drag is a force that opposes or resists motion, caused by collisions of moving objects with molecules in a fluid like air or water. Drag increases if an object increases its speed, has a large cross-sectional area, or if the fluid it is moving through is more dense.

What 4 things affect the drag force on an object?

Some factors that impact the magnitude of air resistance (drag) include the size and shape of the object, the velocity of the object and the air, and other properties of the air such as its viscosity, mass, and compressibility.

What is base drag?

base drag, (aerodynamics) a pressure drag due to flow separation at the base of a projectile or termination of an aircraft fuselage with a flat area, such as is noticeable on the BAE Systems Hawk.

What is drag explain with suitable example?

Drag is defined as the friction in the fluid. Examples: when an aeroplane move it needs to streamline the body to reduce drag because due to high-speed air offer resistance against the motion of plan.

What effects drag?

Drag is associated with the movement of the aircraft through the air, so drag depends on the velocity of the air. Like lift, drag actually varies with the square of the relative velocity between the object and the air.

What things affect drag?

Drag depends on the density of the air, the square of the velocity, the air’s viscosity and compressibility, the size and shape of the body, and the body’s inclination to the flow.

Does a stationary object experience drag?

An object that is stationary with respect to the fluid will certainly not experience any drag force. Start moving and a resistive force will arise.

What objects are affected by drag?

Air resistance is an example of the drag force , which is force that objects feel when they move through a fluid (liquid or gas)….Drag.

What drag force is affected?

Explanation: Drag force is affected by cross sectional area and smoothness. If it is affected by cross sectional area, then it is called form drag. If it is affected by surface smoothness, then it is called as surface drag.

How does drag affect an object?

It makes no difference whether the object moves through a static fluid or whether the fluid moves past a static solid object. Drag is a force and is therefore a vector quantity having both a magnitude and a direction. Drag acts in a direction that is opposite to the motion of the aircraft.
