Lab Assignment 5:  Energy Instructor’s Overview Energy is a key concept in physics.  In this lab we will explore the concepts of potential and kinetic energy and energy conservation.  We’ll first examine a hypothetical roller coaster design to learn more about the interplay of potential and kinetic energy.  In the second part of the lab, we will use a rubber “popper” to directly experiment with energy. This activity is based on Lab 11 of the eScience Lab kit. Our lab consists of two main components.  These components are described in detail in the eScience manual.  Here is a quick overview: In the first part of the lab, you will be presented with a diagram of a rollercoaster.  Based on your knowledge of potential and kinetic energy and energy conservation, you will answer a series of questions on the design.  This activity dovetails well with the Instructor’s Commentary on roller coasters. In the second part of the lab, you will work with a rubber popper to explore concepts such as potential energy, kinetic energy, and energy conservation. Take detailed notes as you perform the experiment and fill out the sections below.  This document serves as your lab report.  Please include detailed descriptions of your experimental methods and observations.  Record all of your data in the table that is provided in this document. Experiment Tips:  ·  Place the popper on a smooth flat surface like a linoleum floor.  I recommend placing the popper on the floor since it travels a good height.  When I initially ran the experiment on my kitchen table, the popper hit the ceiling. ·  I recommend recruiting a lab assistant when you run the popper experiment.  When you turn the popper inside out and place it on the ground, it takes off in short order.  I recommend having another person set the popper up while you time its flight and measure its maximum height.

What causes the roller coaster train to lose energy over its trip? ·  List the points in order of greatest potential energy to least. Popper energy experiment Based on your results from the popper energy experiment, please answer the following questions: 1.  What is the gravitational potential energy of the popper at its average measured maximum height? Use g = 9.8 m/s2, and a mass of 0.01 kg. Potential energy = mgh = 2.  Use the following kinematic equation to calculate the initial velocity of the popper based on how long it is in the air: h = h0 + v0t ‐½ gt2, where the final height h = 0 and initial height h0 = 0 after the popper travels up and down over your measured time t. 3.  127 4.  Use the calculated value for the initial velocity to find the kinetic energy of the popper right as it “pops” up. 5.  Compare your answers for potential energy and kinetic energy.  Are they the same, or close to the same? 6.  Is the energy stored in the popper rubber before it “pops” more or less than the energy the popper has at its total height? Why? Conclusions References

Leaders need to understand how technology influences leadership and plays a role in work, work processes, organizational culture, and performance as organizations move toward a collaborative style that creates flatter organizations, project teams, and other unique traits. In addition, what is perceived to be ethical in one culture may not be perceived to be ethical in another, requiring leaders to understand how to make ethical decisions in diverse groups. In this assignment, you will discusses the ways leaders can meet the future ethical challenges of technology and diversity in organizations.
