Alexis Horton H Physics 9/4/19 Lauren Sam Title: Laser vs. Time Lab Purpose: The purpose of this lab was for us to use trigonometry to determine our percent of error. Hypothesis: My hypothesis is that our percent error is going to be between 5-10%. Procedures/Materials: In order to start the lab, I used two-meter sticks and a laser that had a protractor with a washer on a string connected to it. 1. First, pick a spot on the floor and then measure from where you are to a wall. Record that data, and then use the laser and point it at the corner of the wall you measured to staying at the distance you recorded. 2. From the way you are holding it, subtract that number from 90 degrees. Record your data. After that, use trigonometry to find the height of the wall that you’ve been measuring to, and then put down what you got on your paper. I did three trials for this. 3. For this next part, you need to measure the distance between the two poles on the lab stations. Once you’ve done that, hold the laser at the bottom of one pole,

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.
