work done and energy transfer

• Work done


  Energy transferred when a force moves an object
• Calculating work done


  Force (N) x Distance (m)
• The distance must be in the line of action of the force
• Work is measured in Joules (J) or Newton-meters (N·m)
• Kinetic energy


  Energy of a moving object
• Only the distance in the line of action of the force is relevant for calculating work done
