This procedure consists of making observations, formulating hypotheses, and designing experiments, which in turn lead to additional observations, hypotheses, and experiments in repeated cycles

Circular motion, a type of motion where an object moves along a circular path, introduces the concept of centripetal force, which keeps the object in its circular trajectory.

The positive integer exponent n indicates the number of times the base x is repeated as a factor.
