Motion, simple machines and waves, physics quiz. One of the basic rules for 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.
The ramp increases the amount of work you do.
The object is moved over a shorter distance.
Less force is needed to move the object over a longer distance.
