Question
In the table below, the directions of the constant force F and the displacement Δr are shown. Write in the sign of the work done by the force (positive "+" or negative "-") or "0" if the work done by the force is zero. Write a brief explanation of why each is correct.
Transcribed Image Text:The image presents a table with three columns labeled \( \mathbf{F} \), \( \Delta \mathbf{r} \), and "Sign." The table shows five rows labeled from (a) to (e). Here is the detailed content of the table:
- Row (a):
- \( \mathbf{F} \): An arrow pointing left.
- \( \Delta \mathbf{r} \): An arrow pointing left.
- Sign: No entry.
- Row (b):
- \( \mathbf{F} \): An arrow pointing diagonally left and upwards.
- \( \Delta \mathbf{r} \): An arrow pointing up.
- Sign: No entry.
- Row (c):
- \( \mathbf{F} \): An arrow pointing up.
- \( \Delta \mathbf{r} \): An arrow pointing right.
- Sign: No entry.
- Row (d):
- \( \mathbf{F} \): An arrow pointing diagonally right and upwards.
- \( \Delta \mathbf{r} \): An arrow pointing down.
- Sign: No entry.
- Row (e):
- \( \mathbf{F} \): An arrow pointing right.
- \( \Delta \mathbf{r} \): An arrow pointing diagonally right and downwards.
- Sign: No entry.
This table can be used to analyze the relationship between force (\( \mathbf{F} \)) and displacement (\( \Delta \mathbf{r} \)), potentially in the context of determining the sign (positive, negative, or neutral) of the work done in various scenarios.
