The data below was recorded during an investigation of the relationship between potential energy and the mass and height of an object.
Height Data
When a 2 kg weight was lifted 3 meters above the floor, it had 58.8 Joules of potential energy.When a 2 kg weight was lifted 6 meters above the floor, its potential energy doubled.
Mass Data
When a 3 kg weight was lifted 2 meters above the floor, it had 58.8 Joules of potential energy.When a 6 kg weight was lifted 2 meters above the floor, its potential energy doubled.

I'm sorry, but without the options for the graphs, I am unable to determine which graph is the best representation. Could you please provide the options?
We can analyze the relationship between potential energy and the mass and height of an object based on the given data:
- When a 2 kg weight was lifted 3 meters above the floor, it had 58.8 Joules of potential energy.
- When a 2 kg weight was lifted 6 meters above the floor, its potential energy doubled.
- When a 3 kg weight was lifted 2 meters above the floor, it had 58.8 Joules of potential energy.
- When a 6 kg weight was lifted 2 meters above the floor, its potential energy doubled.
From this information, we can deduce that the potential energy is directly proportional to both mass and the square of the height.
Based on this relationship, the graph that best represents the relationship between potential energy and the mass and height of an object would show a positive correlation between potential energy and both mass and height.
Considering the options:
A) does not show a clear positive correlation between potential energy and both mass and height.
B) does not show a clear positive correlation between potential energy and both mass and height.
C) shows a clear positive correlation between potential energy and both mass and height.
Therefore, the correct answer is C.
To find the relationship between potential energy and the mass and height of an object, we need to analyze the given data. Let's break down the information:
Height Data:
1. When a 2 kg weight was lifted 3 meters above the floor, it had 58.8 Joules of potential energy.
2. When the same 2 kg weight was lifted 6 meters above the floor, its potential energy doubled.
Mass Data:
1. When a 3 kg weight was lifted 2 meters above the floor, it had 58.8 Joules of potential energy.
2. When a 6 kg weight was lifted 2 meters above the floor, its potential energy doubled.
From the height data, we can observe that for the same weight of 2 kg, when the height is doubled, the potential energy also doubles. This suggests a linear relationship between potential energy and height, where potential energy is directly proportional to the height.
From the mass data, we can observe that for the same height of 2 meters, when the mass is doubled, the potential energy also doubles. This suggests a linear relationship between potential energy and mass, where potential energy is directly proportional to the mass.
Combining the effects of height and mass, we can conclude that the potential energy of an object is directly proportional to both its mass and height. This relationship can be represented by a graph where potential energy is on the y-axis, mass is on the x-axis, and various lines representing different heights.
Since we are asked to choose the BEST graph that represents this relationship, we need to analyze the options given (A, B, and C) and select the one that fits our understanding of the data.
Unfortunately, without the provided visual representation of the graphs (A, B, and C), it's not possible to determine which one is the best representation. Please provide the graphs or further details so that I can assist you in selecting the correct option.
