Forces in Everyday Life (Week 7)
Model or Topic Explored: You will create a demonstration of either the free particle (sum
of the forces is equal to zero) or constant force particle (sum of the forces is equal to
mass x acceleration). You have several different options to choose from to create a
scenario, or you may develop one of your own to look at the force balance.

Observables: Unit/Force sensor is attached to a string, string is attached to a weight
(box), the unit moves faster and faster (acceleration)

Measureables: F (sum of forces, N), a (acceleration, m/s/s, or m/ s ¿ , m (mass of

Constants: First experiment = mass of iOLab unit will be constant
Second Experiment = sum of forces will be constant (weight in box)

Problem Statement: First experiment = How does acceleration depend on F?
vi y re
(keeping mass of unit constant)
Second experiment = How does acceleration depend on m? (keeping sum of forces

constant)

Prediction: I think the acceleration will be directly proportional to the magnitude of F.
Also, the acceleration will be inversely proportional to mass of the unit.

Experiment: Procedure, Tools, Diagram of Apparatus: [In this section, please paste a
digital photograph of the items used in your experiment.]
Tools: iOLab unit, eyehook, table, string, box, tape, 4 masses (fishing weights)
Procedure:
1. Gather tools needed
2. Poke hole on side of iOLab unit box
3. Place bolt and nut through the hole
4. Tie string to the end of the bolt and use the nut to tighten string to the box
5. Put eyehook into the iOLab unit
6. Tie other end of string to the eyehook
7. Select force and wheel sensors on the iOLab software
8. Start recording with the empty box and iOLab unit on the table and rezero the
force sensor
9. Let the empty box hang off the edge of the table while holding the iOLab unit

10. Now let iOLab unit go while recording data on the software
11. Catch the iOLab unit at the end of the table before it falls off

12. Press stop on the software
13. Repeat steps 9-12 for a total of 3 times (remember to push record before letting it

14. Once you have collected 3 trials for each set, calculate the average for the 3 trial

results of acceleration and for force
15. Next, repeat steps 9-14, by adding 1 fishing weight to the box at a time (Up to a
total of 4 fishing weights in the box/For a total of 5 different sets)

16. Place the averaged data into a table
aC s
17. Create a graph using the table and fit it with the proper trend line
vi y re
18. Write the math model, make a diagrammatic model, and explain the results in a
verbal representation
19. For experiment #2, repeat steps 9-13, but instead of adding 1 fishing weight to
ed d
the box at a time, you add 1 fishing weight at a time to the top of the unit (Up to a
ar stu
total of 4 fishing weights on top of the unit/For a total of 5 different sets)
20. Once you have collected 3 trials for each set, calculate the average for the
acceleration and add the mass of each weight to the mass of the unit
21. Place the averaged acceleration and the mass into a table
is
22. Repeat steps 17-18.
