Work Done- Physics

Work Done- Physics

1. Calculations

   • Work Done(J)= Force(N) x Distance(M)
     • J~Joules N~Newtons M~Metres

2. When an object is moved by a force work is done on the object by the force

   • Energy transferred = Work done

3. Example

   • How much work is done to pull the lorry a distance of 40 m with a force of 2000 N?
     • Work Done= 2000N x 40m
       • 80,000

4. Energy cannot be made or destroyed, only transferred

5. Energy is measured in Joules.
