1. In bowling, is it better to use a lighter ball than a heavier ball? --- I'm guessing it's better to use a heavier ball because mass is directly proportional to momentum. Is this correct? 2. In billiards, what are the strategies in making a good break? 3. What is the winning strategy for an egg-catching game using raw eggs so it won't break? What is the relevance of the momentum-impulse theorem? --- Those other two, though, I have no idea. Please help. Thanks!
