Quiz and worksheet on using a spring scale to measure weight.

I will solve this quiz worksheet step by step, answering each question based on the image and physics principles.

Question 1: Which letter points to the part of the spring scale that indicates the object's weight?

First, look closely:
- The image shows a spring scale with four labeled parts: A, B, C, and D.
- Part A points to the top ring/handle.
- Part B points to the indicator needle or pointer on the scale.
- Part C points to the body/casing of the scale.
- Part D points to the bottom hook where objects are hung.

The part that indicates the object's weight is the pointer (needle) that moves along the graduated scale to show the measurement. This is clearly labeled as B.

Answer for Question 1: B

Question 2: Which of the following is true of an object's weight?

Next, find information:
Weight is defined as the force exerted on an object due to gravity. It is calculated as mass multiplied by the acceleration due to gravity (W = m * g). Therefore:
- Weight can change if gravity changes (e.g., on the Moon vs. Earth).
- Weight is directly related to mass.
- Spring scales measure weight by measuring the force of gravity on an object.

Review the findings:
- "It never changes" — False, because weight depends on gravity, which varies by location.
- "It is unrelated to an object's mass" — False, because weight = mass × gravity.
- "It is dependent on gravity" — True, this is the correct definition.
- "You cannot measure an object's weight on a spring scale" — False, spring scales are designed to measure weight.

Answer for Question 2: It is dependent on gravity.

Question 3: Complete the following sentence: A object's ___ equals its ___ multiplied by the acceleration due to gravity.

Next, find information:
This is a direct application of Newton’s second law in the context of gravity. The formula is:
Weight = Mass × Acceleration due to gravity

So, the sentence should read: "A object's weight equals its mass multiplied by the acceleration due to gravity."

Review the findings:
Looking at the options:
- weight, mass → Correct
- weight, matter → Incorrect, “matter” is not a measurable quantity like mass
- mass, weight → Incorrect, reverses the relationship
- matter, mass → Incorrect, doesn’t make sense in this context

Answer for Question 3: weight, mass

Final Answers:

1. B
2. It is dependent on gravity.
3. weight, mass

These answers are based on standard physics definitions and the visual cues from the spring scale image.
