Questions and Answers

According to Newton's laws of motion, what happens to a body when it is not acted upon by a force?

  • It decelerates
  • It moves at a constant speed in a straight line (correct)
  • It remains at rest
  • It accelerates
  • What is the relationship between a body's acceleration, mass, and net force?

  • Acceleration minus mass is equal to the net force
  • Acceleration multiplied by mass is equal to the net force (correct)
  • Acceleration plus mass is equal to the net force
  • Acceleration divided by mass is equal to the net force
  • When two bodies exert forces on each other, what is the relationship between these forces?

  • They have different magnitudes and same direction
  • They have the same magnitude and opposite directions (correct)
  • They have different magnitudes and opposite directions
  • They have the same magnitude and same direction
  • Who first stated the three laws of motion?

    What are Newton's laws of motion and how do they describe the relationship between motion and forces?

    <p>Newton's laws of motion are three basic laws of classical mechanics. The first law states that a body remains at rest or in motion at a constant speed in a straight line unless acted upon by a force. The second law states that when a body is acted upon by a net force, the body's acceleration multiplied by its mass is equal to the net force. The third law states that if two bodies exert forces on each other, these forces have the same magnitude but opposite directions.</p> Signup and view all the answers
