What is the equation for work when force and displacement point in the same or opposite direction?

In this tutorial you will learn the formulas that you can use for finding the work that a force does.

Summary

  1. F with an arrow- the force vector pushing the block
  2. W- work
  3. F with no arrow- the strength of the force vector
  4. d- distance
  5. Work is positive when the force is in the direction of motion!
  6. Work is negative when the force opposes the direction of motion
  7. N- Newtons, m- meters
  8. J- Joules

Notes

    1. F with an arrow- the force vector pushing the block
    1. W- work
    2. F without an arrow- the strength of the force vector
    3. d- distance over which force is acting
    4. F with an arrow- the force vector
    1. F with an arrow- the force vector pushing the block
    1. W- work
    2. F without an arrow- the strength of the force vector
    3. d- distance over which force is acting
    1. d- distance
    2. Plugging d=0 into the work equation gives W=0
    3. W- work
    1. N- Newtons
    1. m- meters
    1. N- Newtons
    2. m- meters
    3. J- Joules
