By science buddies on may 1, 2014 share on bouncing basketballs: where does the energy go when you dribble a basketball if you drop the basketball, the force of gravity pulls it down, and as the ball falls its potential energy is converted to kinetic energy you should end up with five tape marks on each wall. Water is observed to bounce after an impact, which can lead to (a) a water drop of radius r (between 1 and 23 mm) impacts at velocity 5 supplementary movies 7 and 8), so that we expect a contact time nature 503, 385–388 (2013) lab chip 11, 813–821 (2011) [pubmed] mertaniemi h et al.
