About the Lecture
The lecture Important Forces: Air Resistance by Jared Rovny, PhD is from the course Force.
Included Quiz Questions
Which statement is TRUE about the drag force on an object moving through the air?
- The drag force increases as the object speed up.
- The drag force decreases as the object speeds up until it reaches terminal velocity.
- The drag force is always equal to the gravitational force as an object speeds up to maintain terminal velocity.
- The drag force is always equal and opposite to the gravitational force.
- The drag force is always equal and parallel to the gravitational force.
Which of the following is TRUE about terminal velocity?
- Terminal velocity reaches when the drag force equals the gravitational force.
- Terminal velocity is the negative acceleration for a stable object.
- Terminal velocity is the fastest an object can ever move.
- Terminal velocity is the square of the velocity of an object.
- Terminal velocity is equal to the drag force at its maximum.
How is the drag force F_d related to the object's speed v?
- F_d ∝ v²
- F_d ∝ v
- F_d ∝ √v
- F_d ∝ v³
- F_d ∝ 1/v
