Written as a textbook chapter review, this worksheet on Newton's three laws of motion is well-organized. You don't necessarily need to have the exact textbook to assign this as homework. Young physicists could either look the information up online, or if you have lectured on the material, simply refer to their notes or textbook. Learners write out and answer a few questions about each law. In a final section, they answer questions about the law of conservation of momentum.
