Question: Read the attached articles and search for at least 3 more references to design and implement a study to find which ball bounces best out of a Tennis ball, sponge ball, table tennis ball, roll-on ball, and a golf ball. The variables to be taken into account are the size of the ball, material, mass, density, compressibility, rigidity of the floor etc. By way of suggestion:
