- Homework Statement
- Draw the graph of ##F=-2x## and calculate the work done from ##[-1,1]##

- Relevant Equations
- Work = area under the graph

The answer key is zero because the areas are above and below x-axis and have equal magnitude so canceling out each other.

But I am confused about the solution

Area 1 is above x-axis but I think the work done is negative since the sign of ##F## and ##x## is opposite. Work done on area 2 is also negative for the same reasoning so my answer would be -2 J

Where is my mistake? Thanks
