The Law of Conservation of Energy
Mass-energy equivalence
Law of Universal Gravitation
Newton's Laws of Motion
What might be considered an exception to the Law of Conservation of energy?
E=mc2 (energy can be "created from mass")
A roller coaster losing potential energy as it goes down a hill

Which of the following best describes this illustration of heat transfer?
Convection
conduction
radiation

Which of the four fundamental forces is the weakest?
strong nuclear force
weak nuclear force
electromagnetic force
gravitational force
Which of the following best represents a magnetic field?
The pull of gravity actually varies over the surface of the earth. Blue spots have the strongest gravity, and red spots have the weakest. Based on Newton's Law of Universal Gravitation, why might this be the case?
Newton said that every action has an equal and opposite reaction.
Newton's Law of Gravitation says that gravitational force is greater the closer two objects are to one another. The bottom of the ocean is closer to the center of the earth.
Gravity cannot be created or destroyed, only changed in form.
