What is Mechanical work?

Work done by a Constant force:

Work done when force and displacement are in the Same direction:

Work done when force and displacement are in Different directions:

For Example:
  • an object may experience a force in one direction while the object moves in a different direction
  • this occurs when a person pulls on a suitcase with wheels and a handle
  • the applied force is directed toward the person’s hips, while the suitcase rolls on the floor in the forward direction
  • the applied force is resolved into horizontal (Fh) and vertical (Fv) components
  • the applied force vector, Fa, makes an angle θ with the displacement vector

​The magnitude of
Fh is given by the equation:


Picture
Since the horizontal component, Fh, is the only force in the direction of the suitcase’s displacement, it is the only force that causes the suitcase to move along the floor.

Thus, the amount of mechanical work (W) done by Fh on the suitcase may be calculated using the equation:
Picture
What about the vertical component of Fa?

  • Fv  does no work on the suitcase because the suitcase is not displaced in the direction of Fv.
  • Since Fv is perpendicular to the suitcase’s displacement along the floor:​
Picture
  •  Therefore, Fv does no work on the suitcase.

​
  • The brick wall does not move while the student is leaning on it
  • Thus, there is no acceleration.
  • If there is no acceleration, there is no net force.
  • Therefore, no work is done.

​
  • The space probe is moving at a constant velocity
  • There is no acceleration, so there is no net force.
  • Therefore, no work is done.

​
  • The textbook does not move while sitting on the shelf
  • Thus, there is no motion.
  • If there is no motion, there is no net force.
  • Therefore, no work is done.
