Questions and Answers

What is work in physics?

  • The energy stored in an object
  • The distance traveled by an object
  • The energy transferred to or from an object via the application of force along a displacement (correct)
  • The speed of an object

    • What is the work done by the gravitational force when a ball is thrown upwards?

  • Depends on the weight of the ball
  • Negative (correct)
  • Zero
  • Positive

    • When does a force do positive work?

  • When it has a component in the direction of the displacement (correct)
  • When it has a component opposite to the displacement
  • When it is applied at an angle to the displacement
  • When it is applied perpendicular to the displacement

    • In which form is work given when the force F is constant and the angle θ between the force and the displacement s is also constant?
