Questions and Answers

When does a force do positive work?

  • When it is perpendicular to the displacement
  • When it has a component in the direction of the displacement (correct)
  • When it is applied to a stationary object
  • When it has a component opposite to the displacement
  • What is work in physics?

  • The energy transferred to or from an object via the application of force along a displacement (correct)
  • The distance an object travels when a force is applied
  • The energy stored in an object when a force is applied
  • The force exerted on an object
  • What happens when a force does negative work?

  • It is perpendicular to the displacement
  • It has a component in the direction of the displacement
  • It doesn't affect the displacement
