Questions and Answers

What is the formula for work when the force F and displacement s are constant and the angle θ between them is also constant?

  • $W = |F| + |s| + \theta$
  • $W = |F||s|\cos(\theta)$ (correct)
  • $W = \frac{|F|}{|s|}\cos(\theta)$
  • $W = |F||s|\sin(\theta)$

    • What type of work does a force do if it has a component in the direction of the displacement?

  • Scalar work
  • Negative work
  • Zero work
  • Positive work (correct)

    • If a force has a component opposite to the direction of the displacement, what type of work does it do?

  • Scalar work
  • Negative work (correct)
  • Zero work
  • Positive work
