Questions and Answers

What type of work does the gravitational force do on a ball as it falls?

  • No work
  • Negative work
  • Variable work
  • Positive work (correct)

    • What is the equation for work in its simplest form for a constant force aligned with the direction of motion?

  • $W = F + d$
  • $W = F \cdot d$ (correct)
  • $W = F - d$
  • $W = \frac{F}{d}$

    • When does a force do positive work?

  • When it has a component opposite to the displacement
  • When it has no component in the direction of the displacement
  • When it has a component perpendicular to the displacement
  • When it has a component in the direction of the displacement (correct)
