Every macroscopic object in the universe follows either Newton’s first law of motion, or Newton’s second law of motion, but never both at the same time. The First Law or Second Law? Assignment provides students with 25 different scenarios and challenges them to recognize each as either a “first law” or “second law” situation.
Some of the scenarios are simple and some are tricky, but even the apparently simple scenarios might generate unexpected classroom debate and reveal hidden misconceptions among students. The First Law or Second Law? Assignment can be used as a formative assessment to check student understanding as Newton’s laws of motion are studied.
