Question

Which of the following is not an example of work?

a. raising a barbell over your head
b. picking up a box off the floor
c. holding a tray in the cafeteria line
d. pushing a box across the floor

Answer 1

It is C. holding the tray

Answer 2

The best answer for this question would be: c. holding a tray in the cafeteria lined. Work is when there is energy that is exerted throughout an object using force and action. Which displaces the measure of the force and the application of that specific action.
