Alexis Horton H Physics 9/13/19 Ja’Leah Caleb Logan Title: 1 st Law of Motion Lab Purpose: The purpose of this lab is to find the amount of force a hanging 550g weight has on two pieces of string. Hypothesis: I predict that we will have an accurate estimate on the amount of force, and the weight on the string that our percent of error is less than 10%. Procedures/Materials: For this lab you will need: 2 Dual Force Sensors, String, a 500g weight, a 50g hook insert, a protractor, and a Logger Pro. 1) First, you must calibrate the dual force sensors by holding the sensor vertically with the hook on the bottom. 2) After that, navigate to the calibrate menu on the LoggerPro, and then press calibrate now. Put in theta ( ) and press keep. Put the hook and weight on the Ɵ sensor and then hold it vertically. Put in 5.39 (this is going to be your given), and then press keep. 3) You’re going to be connecting a string to each sensor. Connect the shorter string

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
