Work Done Equations

• Understand that work is done on an object when a force causes it to undergo displacement.
• Calculate the work done by a force on an object using the equation:

$W = F s$

• Identify the units for work done (joules, J), force (newtons, N), and displacement distance (metres, m).
• Explain that one joule of work is done when a force of one newton causes a displacement of one metre.
• Convert confidently between newton-metres and joules.
• Describe the specific energy transfers involved when work is done.
• Explain how work done against frictional forces acting on an object causes a subsequent rise in the object's temperature.
