Questions and Answers

Who first stated the three laws of motion?

  • Albert Einstein
  • Nicolaus Copernicus
  • Isaac Newton (correct)
  • Galileo Galilei
  • What does Newton's first law of motion state?

  • A body will change its direction if a force is applied
  • A body will change its speed if a force is applied
  • A body's momentum changes when a force is applied
  • A body remains at rest, or in motion at a constant speed in a straight line, unless acted upon by a force (correct)
  • What does Newton's second law of motion state?

  • If two bodies exert forces on each other, these forces have the same magnitude but opposite directions
  • A body remains at rest, or in motion at a constant speed in a straight line, unless acted upon by a force
  • A body's momentum changes when a force is applied
  • When a body is acted upon by a force, the time rate of change of its momentum equals the force (correct)
  • What does Newton's third law of motion state?
