Module 2. Physics

What work is done if a force of 100 N moves a body 15 metres?

  • 150 kJ.
  • 1.5 kJ.
  • 0.15 J.

Explanation

Work equals force times distance: 100 N x 15 m = 1500 J, which is 1.5 kJ. The 150 kJ distractor is out by a factor of 100 from a misplaced unit conversion.

Work [J] = force * distance
