Book 28, Question 25
How can you test ball physics in your own backyard?
Choose one question, like how the angle changes the distance.
Use the same ball and throw each time. Mark landing spots with chalk or tape. Change only one thing at a time, such as angle, spin, or ball type. Try each three times and write the results in a table. Make sure you have lots of space, no windows nearby, and a grown-up to watch.
