Physics
Newton's Second Law
Verify Newton's second law ... acceleration proportional to net force and inversely proportional to mass.
Mission
Verify Newton's second law "The acceleration of a body as produced by the net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the body."

Mind-Blowing Fact
My dog ate my homework.
Isaac Newton's dog set his lab on fire, causing 20 years of research to be set alight. Newton's reaction to this was his famous exclamation: "O Diamond, Diamond, thou little knowest the mischief thou hast done."
