Question
TMCC PHYS-1 HOMEWORK Understanding Work and Energy Eight boxes, A thru H, move a distance Ax across a tabletop while a loro is exoned on each. 2F axed 1. Which (if any) of the examples shown above are physically possible (could actually happen)? For which (if any) of the physically possible cases, does the force shown do a positive amount of work on the box? (List all.) Note that you are only asked about the work done by the force shown in the figure. 2. For which (if any) of the physically possible cases, does the force shown do a negative amount of work on the box? (List all.) the force shown in the figure. 3. Note that you are only asked about the work done by TMCC PHYS-1 Lab Homework Page 1 of 6Explanation / Answer
1) A, C, E, F can be physically possible.
in other cases there is no force in the direction of displacement.
2) In A, C, E, F positive work is done because the angle between displacement and force is less than 90 degree.
3) In G and H, the work done is negative because displacement is opposite to the force.
