None of our students were alive when Michael Jordan made his famous dunk from the free throw line. Yet many have seen pictures of it (they’re copyrighted) and tried to imitate it on playgrounds, in driveways, and in gyms. How much hang time did Michael Jordan have when he jumped? What are the forces influencing hang time? And what would it be like to jump on the moon? All of those questions and more are covered in a new TED-Ed lesson, The Math Behind Michael Jordan’s Hang Time.
