Question 1 Report
A student pushes different objects with different forces along a flat surface. The table shows the results.
| Object | Force (N) | Distance (m) | Work done (J) |
|---|---|---|---|
| P | 10 | 3.0 | 30 |
| Q | 20 | 2.0 | 40 |
| R | 15 | 4.0 | ? |
| S | 25 | 2.0 | 50 |
What is the work done on object R?
Work done is calculated using:
\[ W = F \times d \]
For object R:
\[ W = 15 \times 4.0 = 60 \text{ J} \]
This is consistent with the pattern shown for the other objects: P gives \( 10 \times 3.0 = 30 \text{ J} \), Q gives \( 20 \times 2.0 = 40 \text{ J} \), and S gives \( 25 \times 2.0 = 50 \text{ J} \).
