Questions and Answers

Which of the following best describes Newton's first law of motion?

  • For every action, there is an equal and opposite reaction.
  • An object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force. (correct)
  • Force equals mass times acceleration.
  • The change in motion of an object is proportional to the force impressed and is made in the direction of the straight line in which that force is impressed.

    • What is the significance of Newton's second law of motion?

  • It explains the relation between an object's mass, its acceleration, and the applied force. (correct)
  • It states that an object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
  • It defines the principle of action and reaction.
  • It describes how the velocity of an object changes when it is subjected to an external force.

    • According to Newton's third law of motion, what happens when a force is exerted on an object?

  • The force applied will cause a change in the object's mass.
  • The object exerts a force of equal magnitude but in the opposite direction on the original object. (correct)
  • The object will move in the direction of the force applied, regardless of its mass.
  • The force applied on the object will result in an immediate change in its velocity.

    • When can we say that an object is in equilibrium?
