Work

• Equation that links work done, force and distance?

  Work Done = Force x Distance

  W = Fs
• What is work done?

  When energy is transferred from the object doing the work to another form

  • if a book is lifted 1m in the air, and 2m to the right
  • work is done when moving 1m vertically, as that is in the direction of the force
  • energy is transferred from your muscles to the book, increasing its gravitational potential
• One joule of work is done when a force of one newton causes a displacement of one metre

  1 joule = 1 newton-metre
• Work done against frictional forces causes a rise in temperature of the object
