Define drag force in your own words.
Think about what happens when you stick your hand out of a moving car window.
What does the coefficient of drag (Cd) describe?
This coefficient varies from one shape to another.
What does the coefficient of drag (Cd) depend on?
Consider how different objects experience varying resistance.
True or False: Lift force always acts in the same direction as the flow.
Remember how airplane wings generate lift.
A car with a frontal area of 3 m² and a drag coefficient of 0.3 is traveling at 30 m/s. Calculate the drag force acting on the car.
Make sure to convert your units appropriately.
If a cyclist can reduce their Cd from 0.9 to 0.6 by changing positions, quantify the potential speed increase if power output remains constant.
Consider the relationship between power, velocity, and drag.
