Drag And Terminal Velocity

Question 1

What is drag?

Answer 1

When an object experiences a resistive force when it moves through a fluid.

Question 2

What factors affect drag?

Answer 2

•Density of fluid
•Velocity of the object
•Cross-sectional area of the object
•Shape of the object (amount of streamlining)
•Texture of the surface of the object

Question 3

By combining all the factors of drag, what will be the equation for force?

Answer 3

F= ½ ρCdAv²

Question 4

What will happen to the drag force if the velocity is doubled?

Answer 4

The drag force will become four times as great (since F ∝v²
