Test your understanding of drag and resistive forces with 5 practice questions.

Practice Questions

Question 1

What is the differential equation for an object of mass $m$ falling under gravity with a linear resistive force $F_R = -bv$?

Question 2

If an object is falling through a fluid and experiences a quadratic resistive force, how does the drag force change if the object's speed is quadrupled?

Question 3

What happens to the acceleration of an object falling through a fluid as it approaches terminal velocity?

Question 4

In the context of resistive forces, which of the following factors does NOT affect the magnitude of a quadratic drag force?

Question 5

For an object falling with a linear drag force, what is the expression for terminal velocity?
