Questions and Answers

What is the formula for work when the force and displacement vectors are constant?

  • $W = |F||s|\cos(\theta)$ (correct)
  • $W = |F||s|\sin(\theta)$
  • $W = |F| + |s| + \theta$
  • $W = |F| - |s| - \theta$
  • When does a force do negative work?

  • When it has a component in the same direction as the displacement at the point of application
  • When it has no component in the direction of the displacement at the point of application
  • When it has a variable magnitude
  • When it has a component opposite to the direction of the displacement at the point of application (correct)
  • What is the SI unit of work?

  • Newton (N)
  • Coulomb (C)
  • Watt (W)
  • Joule (J) (correct)
