#### Questions and Responses

**i. Does the work done by gravity depend on the path taken? Explain.**

Response:
[Answer not provided in the image]

**ii. Is gravitational force conservative or non-conservative? Why?**

Response:
The handwritten answer in the image reads:
"Conservative force because [insufficient context]." 

**iii. Does the speed of the skater depend on its mass?**

Response:
The handwritten answer in the image reads:
"No because mass doesn’t affect speed directly."

---

#### Analysis:

- For question **i**, the worksheet is asking whether the work done by gravity is path-dependent. In classical physics, the work done by gravity is considered independent of the path taken. It depends only on the initial and final heights of the object.

- For question **ii**, which asks whether the gravitational force is conservative or non-conservative, the provided answer states that gravitational force is conservative. In physics, a conservative force is one where the work done moving a particle between two points is independent of the path taken. The gravitational force is indeed conservative.

- For question **iii**, the worksheet queries the relationship between the skater’s speed and its mass. The student's response is that the mass does not affect speed directly. This would typically align with the principle that in a vacuum (where there is no air resistance), all objects fall at the same rate regardless of mass due to the uniform acceleration of gravity.
