Question

in order to be considered work, the components that must be present are

Answer 1

W=Force x Distance...so you need those two components and the force cannot e perpendicular to the motion.

Answer 2

displacement
I know that work must have a horizontal displacement so lifting a book is not considered a work? (If my memory serves me right)

Answer 3

Lifting a book is doing work....since the force is in the direction of motion.

Answer 4

But the distance being calculated is based on the x-axis. Therefore any force in any direction will be multiplied by 0 if the distance is only found in the y-axis. Therefore producing a 0 for an answer. xD

Answer 5

As long as some of the applied force is in the direction of motion, work is being done. When lifting a book, you are definitely doing work...however, the **net work** is 0 because gravity does the same amount of work in the opposite direction.

Here, I found this example which may help: http://www.batesville.k12.in.us/physics/phynet/mechanics/energy/lifting_a_book.htm

Answer 6

for work you just need is displacement and a non-zero force component in the direction of the displacement.
