Alexa Carter Margaret Turner Natalie Lim Tai Nguyen Lab 5 – Work and Energy Purpose: To demonstrate the motion of objects with uniform acceleration, with emphasis on work, energy and its components. Introduction: We are going begin by properly setting up the cart track, making sure all markings are indicated and all angles are measured. LoggerPro and LabPro will be utilized for this experiment. Data will be collected by pulling on the sled parallel to the track with a constant force and speed for a distance of 80 cm. This exercise will be repeated for a total of 6 different angles. Finally, the mass of the wooden sled and each slotted mass will be calculated. Incline Work (J) Potential Energy (J) % loss in Total Work 1 3.68 0.256 -93.04 2 3.92 0.645 -83.55 3 4.48 1.36 -69.64 4 5.2 2.04 -60.77 5 5.84 2.89 -50.51 6 6.56 3.56 -45.73 Analysis: Work =Fd W1 = (4.6 N)(.8m) = 3.68 J ࠵? ! = mg D h ࠵? ! 1 = (1.66625࠵?࠵?)(9.8)(0.0157࠵?) = .256 ࠵?
Percent loss = (3.68 J) – (.256 J) / (3.68 J) x 100 = 93.04% Reflection: 1. This could be a reasonable estimate because in this case you would pick an estimate +/- 0.0005m to the nearest line on the meterstick. This could also be a gross underestimate
