Introduction
Throw a ball in the air and use the iPhysics app or Logger Pro (or similar) to track the motion. Use a basketball and compare it to a table tennis ball. Does it fit as expected?
Guiding Questions
- What quadratic model describes the path of a thrown ball, and what do its coefficients mean physically?
- Film or photograph a projectile and fit a parabola to its path. How good is the fit?
- How do launch angle and speed change the range and maximum height? Find the angle that maximises range.
- Where does the simple model break down — for example with air resistance or spin?
