Questions and Answers

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

  • $W = |F| \cdot |s| \cdot \tan(\theta)$
  • $W = |F| \cdot |s| \cdot \cos(\theta)$ (correct)
  • $W = |F| \cdot |s| / \theta$
  • $W = |F| \cdot |s| \cdot \sin(\theta)$

    • What is the SI unit of work?

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

    • In its simplest form, for a constant force aligned with the direction of motion, what is the formula for work?

  • $W = |F| + |s|$
  • $W = |F| / |s|$
  • $W = |F| - |s|$
  • $W = |F| \cdot |s|$ (correct)
