Question

We cannot consider something to be work unless (2 points)
force is applied to an object resulting in balanced forces
forces that caused the action were unbalanced and the action occurred in the opposite direction
action was equal to the reaction and was the result of a balanced force
force applied causes movement of an object in the same direction as the applied force

I believe the answer is A

Answer 1

Work = Force * Distance

Answer choice A says that you're applying a force that results in balanced forces.
So you're pushing a box with say a force of 50N and someone else is pushing on the opposite side with 50N to balance the force.
The net force is 0.

Is any work being done on the object if the net force is 0?

Answer 2

I redid my work and got C

Answer 3

What work did you redo?

You have a box


You push on the box with a force of F. Which direction is the box moving in?
Does the box move in the same direction as the force or does it move in the opposite direction of the force?

Answer 4

the same

Answer 5

exactly!

Answer 6

The problem with answer choice C is the same as the one I mentioned with A.

If there's balanced forces, then there is no work being done

Answer 7

ahhhhhh

Answer 8

So then I choose D

Answer 9

You got it!

Answer 10

Thank you for the help!

Answer 11
