D03 Friction Forces Lab Report Sebastian Tic Vargas, Dr. Shanahan, Physics, 12/11/23 1

1 P URPOSE What are you trying to determine?I'm attempting to ascertain how variations in mass affect the force required to push against other forces. In addition to estimating the amount of friction that would result from various forces coming together. Additionally, this allows one to observe how the force would vary based on the mass in relation to other masses. 2 H YPOTHESIS What do you think the outcome will be? Why do you think this will occur? A hypothesis is not a guess, but a prediction based on scientific reasoning. I assume the outcome of this experiment would be that when the mass of an object rises the more force would be needed to push against the thing in general. Nothing can just move, in my opinion, especially if its mass is larger than the force pushing it. 3 V ARIABLES Dependent Variable(s)/Independent Variable(s)/Control Group The man who is pressing the kilograms while changing the newtons is the dependent variable being used. 2

Anything that comprises the box, refrigerator, kid, other man, trash can, and present is an independent variable. The number of newtons used to push important other variables is the controlled variable. 4 M ATERIALS List ALL the materials that will be and was used in the experiment. Applied force using the measure of newtons, box, fridge, child, other man, trash can, present, and man pushing the aid objects. 5 P ROCEDURE Write down step by step instructions in order to perform the experiment. 1. To begin, investigate the net force, motion, friction, and acceleration modes of the simulation. 2. Determine the independent, dependent, and controlled variables in addition to the hypothesis. To find out if your hypothesis will meet the requirements, consult your teacher or consult the ASUPD Lab Report Template. 3. Pick the "friction" mode and enter the values, masses, forces, and total of forces. 4. Press the box, which is the initial object, until it moves quickly, and then release it. Your kinetic friction value, which should be 94 N for your initial object, is the friction force indicated by the red arrow. Note this down in the following chart. 3

5. Determine the gravitational force. To accomplish this, multiply the object's mass by 9.81m/s/s. In the graphic below, note the mass and the gravitational force. 6. The support force exerted on an object in contact with a stable surface is known as the normal force. The floor is applying a typical force to your chair if you are working in this lab while seated. This normal force counteracts the force of gravity and keeps you from falling through the floor. Accordingly, for the following chart, the normal force and the gravitational force will always have the same magnitude but different directions. Enter the value of this normal force in the table below. 7. For every item in the chart, repeat steps 4 through 6 once more. Put an X through the data if the object remains motionless despite applying 500 N of force, as this indicates that the kinetic friction cannot be measured (not moving). 6 D ATA O BSERVATIONS 7 Object(s) Mass ( k g ) Force of Gravity (N) Normal Force (N) Kinetic Friction (N) 1 Box 50kg 490.5kg 50kg 94N Man 80kg 784.8kg 80kg 150N Girl + 1 Box 90kg 882.9kg 90kg 170N 4

8. Record the data or information gathered while doing the experiment, as notes, charts, graphs, or sketches from the experiment. Here are tips for creating charts and graphs using Google Sheets. You can add a chart or graph from a Google Sheet into a Google Doc. 8 R ESULTS Summarize your data observations. According to the data, a heavier object will require a greater (Newton) force to be pushed. 9 C ONCLUSION Use the results to answer the purpose of the experiment. Prove or disprove your hypothesis. 6

In conclusion, my theory held true because I mentioned that greater force would be required to move a heavier object. 10 F UTURE R ECOMMENDATIONS Consider improvements to experimental design and impact for future related experiments. I hope to be able to change the pushing force and weight of the person in the future. 7
