What is work?

In this tutorial you will learn what work means and when work is zero.

Summary

  1. distance- the distance over which the object moves
  2. F with an arrow- force vector
  3. d with an arrow- displacement vector, which points in the direction of motion

Notes

    1. d with an arrow- the displacement vector, which points in the direction of motion
    2. F with an arrow- the force vector pushing the block
    1. d with an arrow- the displacement vector, which points in the direction of motion
    2. F with an arrow- the force vector opposing the motion of the block
    1. A force that is perpendicular to an object's motion does zero work on that object, no matter what!
    2. Force that make a 90 degree angle to the direction of motion are perpendicular forces
    1. d with an arrow- the displacement vector, which points in the direction of motion
    2. F with an arrow- the force vector perpendicular to the motion of the block
    1. Force that make a 90 degree angle to the direction of motion are perpendicular forces
