Physics Quiz: Motion, Simple Machines, And Waves - Quiz

Are you ready for this motion, simple machines, and waves physics quiz? One of the basic rules of physics is that for every action, there is a reaction. Simple machines have been in use for the longest time ever in the building of the pyramids. Power is the rate at which work is done, and machines increase this rate by a significant amount. Take up this quiz and get to see how much you know about power and motion.
