Lesson: Drag and Terminal VelocityPhysics
In this lesson, we will learn how to calculate the drag force acting on objects moving at various speeds through various fluids.
Sample Question Videos
By what factor does the drag force on a car increase as its velocity increases from 65.0 km/h to 110 km/h?
A skydiver with a mass of 80.0 kg falls through air that has a uniform density of 1.23 kg/m3. The skydiver has a surface area of 0.140 m2 and a drag coefficient of 0.690. What is the skydiver’s terminal velocity?
A boater and motor boat are at rest on a lake. Together, they have a mass of kg. The thrust of the motor provides a constant force on the boat of 40 N in the direction of the boat’s motion. If the value of resistive force of the water in newtons is two times the value of the speed of the boat in meters per second, find the limiting speed of the boat.
