April 2, 2017
To begin building my lemon battery, I first gathered all the necessary material which was 2 pennies, a
lemon, foil, and paper clips. I then cut the foil into rectangular trips
Fusion is combining two or more pieces into a single entity. Fission is the breakup of nuclei from heavier
into lighter nuclei.
An everyday life source of radioactivity consists of the sun, about 13 percent. Earth itself is also a source
Atoms are made up of protons, which are positive charge, and neutrons, which are neutral charge, in the
center in a nucleus. Outside of the nucleus an atom has negative charge particles called electrons, which
are the same size as protons.
An electric fie
At a given temperature, there is an amount of energy in the motion and bonds of atoms and molecules
that make up that material. All that energy being used gives us maximum possible efficiency.
A heat engine is not a 100% efficient. In order for it to be e
Using terminology from the lecture material, what is electricity?
2. The original scientific definition of electricity is the study of charge and the motion of charge.
1. Using terminology from the lecture material, describe how a
What does temperature measure? What are some of the ways temperature is
measured? Is there a difference between temperature and heat?
Temperature measures kinetic energy. When measuring temperature, you are measuring
how fast the molecules i
Energy is work, energy is the ability to do work.
Energy is measured in Joules. An example of energy is our heart rate, one single heart rate is equal to
one joule. The smallest size of energy you can find is the size of the universe.
There are several ch
