Question

Air resistance increases as an object begins to move faster.
True or False.
If not true, is it velocity rather than the speed of the object. If yes, explain why?

What does air resistance depend on? List down the factors.​

Answer 1

Answer:

True. Air resistance increases as an object begin to move faster.

Explanation:

The force of air resistance is proportional to the square of the velocity of the moving body. Its equation is given as:

                                      Fₐ ∝ v²

If a body increases its velocity it will also increase the air resistance. This resistance produced will always be in the opposite direction of motion of the body.

Air resistance depends on the following factors:

• The area of cross-section of the body.
• The shape of the body.
• The density of air.
• The velocity of the body.
