Physics 6 Tutorial 10 - Bernoulli Effect and Coefficient of Drag

Home

Summary

It's an initially strange notion that pressure and energy density are the same thing.  However we will see how this concept leads us to the Bernoulli Effect, which explains why balls in games can take curved paths.  We will also look at the coefficient of drag, which affects the paths of projectiles, among other things.  We will, as an extension, have a look at the skin friction.  We will look at some simple models using sporting examples.
