Part 1: Make a graph of each set of data. For the first set, plot the start location data on the x-axis and the box's average slide distance on the y-axis. For the second set of data, plot the mass of the marble on the x-axis and the average distance the box slides on the y-axis.
Four start locations were chosen for this experiment. Why was the potential energy of the marble different at each location?
What happened to the potential energy as the ball rolled down the ramp?
Why did the box slide backwards when the marble hit it?
What kind of energy did the box have as it was sliding? Where did this energy come from?
What is the relationship between the marble's starting position and the distance the box slid?
Part 2:
All the marbles started at the 40-cm mark in this experiment. Were their potential energies the same? Why or why not?
Comparing the marbles, was there any difference in the average amount that the box slid after catching the marble? What is the relationship?
Do all of the marbles have the same amount of kinetic energy at the end of the ramp? How can you tell?
Write a summary paragraph discussing this experiment and the results. Use the following questions and topics to help guide the content of your paragraph.

According to your data, was your hypothesis for each experiment correct? (Be sure to refer to your data and graphs when answering this question.)
Summarize the conclusions that you can draw from this experiment. Use the questions above to guide your ideas.
Summarize any difficulties or problems you had in performing the experiment that might have affected the results. Describe how you might change the procedure to avoid these problems.
Give at least one more example from real life where the principles demonstrated in this lab are evident.

Here is my project that I turned in for this assignment :) It has all the answers including the graph, answers to the questions, and the summary paragraph. I also labeled the parts to make it easier for you see which part is which. Lastly I'm very sorry if my handwriting is not readable for you :( but I tried my best to help.

If you have anymore questions regarding the project, please don't hesitate to comment and ask! I will do my best to answer ASAP.

Here's a copy paste of the answer above! Much love <3

Explanation:

Four start locations were chosen for this experiment. Why was the potential energy of the marble different at each location?

-This is because the higher it is located, the higher potential energy it possesses.

What happened to the potential energy as the ball rolled down the ramp?

-Potential energy decreases.

Why did the box slide backwards when the marble hit it?

-Due to force from the marble.

What kind of energy did the box have as it was sliding? Where did this energy come from?

-The box possesses kinetic energy and it came from the marble's force/impact.

What is the relationship between the marble's starting position and the distance the box slid?

-The higher the potential energy the further the distance the box will slide.

All the marbles started at the 40-cm mark in this experiment. Were their potential energies the same? Why or why not?

-Their potential energies were the same. This is because they are all located at the same spot.

Comparing the marbles, was there any difference in the average amount that the box slid after catching the marble? What is the relationship?

-Yes, there was a difference. The relationship is the higher kinetic energy it possesses, the stronger the impact it has which will then lead to the box sliding further away.

Do all of the marbles have the same amount of kinetic energy at the end of the ramp? How can you tell?

-They DO NOT have the same amount of kinetic energy. I can tell because the higher the mass it has, the higher kinetic energy it possesses. The distance shows the result.

According to your data, was your hypothesis for each experiment correct? (Be sure to refer to your data and graphs when answering this question.)

-According to my data, both of my hypothesis for each experiment are correct. For the first experiment, my hypothesis was "40cm (location) will move the box the most." which was in fact correct because the average distance was the furthest of all. Same thing for the second experiment. My hypothesis for the second experiment was "the larger the mass of the marble, the further the distance of the box." This hypothesis is also correct. For me, the difficult part in preforming this experiment was finding the average distance. One example of a real-life situation that relates to this experiment is a car crash on a hill.

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
