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.

Roller coaster exercise
Consider the
following roller coaster layout taken from the eScience manual:
[img width="475" height="221" src="file:///C:/Users/srarin/AppData/Local/Temp/msohtmlclip1/01/clip_image002.jpg" alt="Description: RollerCoasterDiagram" v:shapes="Picture_x0020_1">
Based on your
understanding of energy concepts, please answer the following questions. Make sure to include detailed physical
arguments.
· What happens to the roller coaster’s
kinetic energy between points B and C? What
happens to its potential energy between these points?
· Why is it important for A to be higher
than C?
·
125
· If the roller coaster starts at point A,
can it ever go higher than this point? 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?

Case study
Ann, a community nurse, made an afternoon home visit with Susan and her father. After the death of her mother, Susan had growing concerns about her father living alone. "I worry about my father all the time. He is becoming more forgetful and he has trouble seeing. Mom used to take care of him. I am not sleeping and I am irritable around him. Yesterday I shouted at him because he wouldn't let me help him with his laundry. I felt terrible! I am at my wits' end! My brothers and sisters do not want to put dad in a nursing home but they are not willing to help out. As usual, they have left me with all the responsibility. I work part time and have two small children to care for.” Susan's father, Sam, sat quietly with tears filling his eyes. He was well nourished and well-groomed but would not make eye contact. Nurse Ann noticed that the house was clean and orderly. A tray in front of the TV had the remains of a ham sandwich and glass of ice tea. Mail was piled up, unopened on a small table near the front door. There was only one car in the driveway and the yard was in need of attention.
What questions does Orlando’s theory guide the nurse to consider in caring for Susan and Sam?
Develop a family plan of care from the perspective of Orlando.
Explore the 1950 and 60’s in the United States:
Explore was happening in the United States during this time (culture, social, economics, struggles)
What did nursing look like during this time (what were their jobs like, responsibilities, dress, autonomy, respect)
What is the most influential accomplishment in nursing theory from the 1950’s and 1960’s?
