Question 1 While at a museum visit, Clara, Luis and Cami learned that the planet Venus is called Earth's sister. This is because it is similar in size to Earth. They also learned about different types of forces acting on the planets. At the end of the field trip, they were presented with an interactive table that compared the gravitational forces that were calculated between different objects and each of the two planets, Earth and Venus.

Question

Question 1 While at a museum visit, Clara, Luis and Cami learned that the planet Venus is called Earth's sister. This is because it is similar in size to Earth. They also learned about different types of forces acting on the planets. At the end of the field trip, they were presented with an interactive table that compared the gravitational forces that were calculated between different objects and each of the two planets, Earth and Venus.
The museum guide asked the class, "What causes the differences in gravitational force of objects with the same mass on Venus and Earth?"

Clara, Luis and Cami each made a claim.

Clara: "Objects will feel a greater gravitational force on Earth, because Earth has more mass than Venus."

Luis: "Objects will feel the same gravitational force on Venus and Earth."

Caml: "Objects will feel a greater gravitational force on Venus, because Venus has less mass than Earth"

Use the chart shown below to gather data to support ONE of the claims.

Based on the information from the table whose claim do you support

A Clara
B Luis
C cami

Question 2

Write an argument that would help the other two classmates understand why you support the claim. Please make sure you respond in CER format:

1. Include a claim stating which classmate you support.

2. Include data as evidence to show how the mass of the object is related to gravitational force. Provide two examples from the table. Be sure to include the mass and gravitational forces when comparing objects.

3. Reasoning that supports the claim you chose by describing the conditions under which objects experience gravitational force.

GPT-4o mini · Answer

### Question 1 I support **A Clara's claim**. ### Question 2 **Claim:** I support Clara's claim that objects will feel a greater gravitational force on Earth because Earth has more mass than Venus. **Evidence:** The data from the table demonstrates that the gravitational forces acting on objects are different on Earth and Venus. For instance, when a backpack of 10 kg is placed on Venus, it experiences a gravitational force of **80 N**. In comparison, the same backpack on Earth experiences a gravitational force of **98 N**. Another example is a brick that weighs 15 kg; on Venus, it experiences a gravitational force of **120 N**, while on Earth, it experiences **147 N**. **Reasoning:** The difference in gravitational force on Earth and Venus can be explained by the mass of each planet. Gravitational force is directly related to the mass of an object and the mass of the planet exerting the force. Since Earth has a greater mass (1 Earth mass) compared to Venus (0.8 Earth mass), it produces a stronger gravitational pull on objects. Thus, regardless of the size of the object, it will experience a greater force due to the stronger gravitational pull from Earth. Hence, Clara's claim that objects feel a greater gravitational force on Earth is consistent with the data presented.
