Bowl+Me+Over



The Objective: During this exercise you will determine instantaneous speed, average speed, momentum and acceleration of a rolling object. You will be able to explain the difference between instant speed and average speed. You will be able to determine the acceleration of a rolling object. You will be able to apply your knowledge of forces to determine how acceleration and momentum can be equal even in objects of different masses. Use critical thinking strategies to determine how an object of lesser mass can have equal momentum and experiment with these objects to prove your hypothesis. Materials Needed: 7.26 kg bowling ball 3.63 kg shot-put Premeasured and properly marked lane for rolling Stopwatches
