Math and Physics

If I’m tutoring someone who’s taken first-year calculus, and I ask if he can take the derivative of the function x(t) = 100 – 16t2, he’ll say sure, it’s x'(t) = -32t. Now I tell him, OK, that function gives the position of an object dropped off the roof of a building 100 feet high at t seconds after it’s released. All you’re doing is applying the math you already know to stuff in the real world.
