Questions and Answers

What can be inferred about the relationship between forces and motion from the given text?

  • Forces can change the shape and size of objects
  • Forces always result in motion
  • Forces can only change the direction of motion
  • Forces can change the magnitude of velocity of an object (correct)

    • Why does a box not move when a small force is applied to push it?

  • The box is immovable
  • The box is too heavy to move
  • The pushing force is not strong enough
  • Friction balances the pushing force (correct)

    • What happens when the pushing force applied to a box becomes bigger than the friction force?

  • The box accelerates rapidly
  • The box moves faster
  • An unbalanced force causes the box to start moving (correct)
  • The box stops moving
