Read the following scenario and decide if it is a hypothesis, theory or law. John is an amateur astronomer who is in his second semester of high school physics.
Accordingly, he knows that objects in motion remain in motion and move at constant
velocity in a straight line until some force acts on them. John observes that all of the
planets in this solar system orbit the sun in approximately circular orbits. In addition,
the farther a planet is from the sun, the longer it takes for that planet to complete one
orbit. John discusses his observations with like-minded friends, who also observe and
verify what John has seen. Based on these consistent observations from many different
people, John concludes that there is gravity in outer space. Is this conclusion a
hypothesis, theory or law?
