Unit 8: Newton's Laws of Motion

Problem Set A

 

Overview:

Problem Set A targets your understanding of Newton's second law of motion and of the distinction between mass and weight. There are a few routine problems and several more complicated multistep problems. The mathematical rigor of the problem set is not high; most student difficulties will lie in the area of conceptual misunderstandings. There are at least four skills needed to be successful on Problem Set A:
