Here are two misconceptions that persist far beyond high school. They surprise even physicists and engineers!
Attach a ball to a bungee cord and swing it in a horizontal circle over your head. What path will the ball take if you release the cord?
We’ve all been taught that it will continue in a straight line* tangent to the circle. That’s wrong!
