Phys 211 Lab: Nittany Adventure II (Conservation of Energy) Reading: Knight: Chapter 10 Conceptual Understanding Goals: By the end of this laboratory, you should be able to: (1) Calculate the kinetic energy, elastic potential energy, and gravitational potential energy for an object. (2) Use Hooke’s Law to relate the spring constant of a spring to its restoring force and its extension. (3) Use conservation of energy to relate the total energy of a system at one point to the total energy of the system at another point. (4) Use conservation of energy to determine the energy transferred into thermal energy due to dissipative forces such as friction. Laboratory Skill Goals: By the end of this laboratory, you should be able to: (1) Predict the speed of a cart under the influence of a spring and gravity. (2) Draw reasonable conclusions about the motion of an object based upon data. (3) Use Excel to fit data to a line. (4) Using zoom to connect with TA’s to ask for directions and approval.

Physics 211: Online Lab Report Template Nittany Adventure II – The Conservation of Energy Grading rubric : 90 points 80 points 70 points 0 points Lab Content Lab handed in completed by Friday night. Physics is largely correct. Lab handed in completed by Friday night. A few physics errors. Lab handed in completed by Friday night. Contains large physics errors. Lab not handed in 10 points 5 points 0 points Discussion board Participation in Discussion board (post by Tuesday and reply by Friday) completed. Participation in Discussion board (post by Tuesday) – no reply No Discussion board post. Enter your name as it appears in your PSU registration, no nicknames please. Name: Mahek Shah Section # 35 When you get to the “check with a TA” it is a good time to post on your group discussion board. Post a question, double check an answer. After you post, you’ll see other students’ questions and you can help answer them. You may log into zoom to “check with TA” at anytime, or to work on this together as a group. TA’s and the group-chat room are available 8AM-8PM on Zoom Monday-Thursday to help if you get stuck or need a nudge. You are developing a new ride for your amusement park, Nittany Adventure , pictured below. The car (and riders) bounce up and down the ramp, hence the name Nittany Bouncer . You will need all your understanding of force and energy to successfully characterize the behavior of this ride.
