Masterpiece Theater: Energy Kills

In the most recent physics unit, we learned various things about energy. We learned that energy can be transfered from one object to another and has the ability to bring about change. Perhaps most importantly, we learned that energy is conserved from initial to final states. This means that unless work is done, initial energy will be equal to final energy due to energy conservation. Energy can't disappear, it can only transfer to other objects through work, such as applied energy (initial state) and friction (final state). The three types of energy we learned about were potential energy, kinetic energy, and elastic energy. Potential energy usually refers to potential energy due to gravity, kinetic energy occurs when an object is in motion, and elastic energy occurs when energy is stored in an object with elastic tendencies, such as springs and bouncy balls. The method of energy transfer we learned about is work. Energy is transferred when energy enters or exits a system. We learned how to draw bar graphs and energy flow diagrams to represent the type of energy present in a system.
Work represents the amount of change a force produces when it acts on an object, and is equated as W=FX, if the force is acting in the same direction as x. If F and X are perpendicular, then no work is done. Power is the rate at which work is performed, and P=W/T.
Kinetic energy is equal to 1/2mv^2. Potential energy is equal to mgh. Elastic potential energy is equal to 1/2kx^2, with k representing the spring constant. We also learned that the net work performed on a body is equal to the difference between initial and final energies, and that mechanical energy is equal to the sum of the potential and kinetic energy found in a system.
Now that the knowledge base has been etablished, I will delight my readers with a thrilling
tale of physics.

"Edith, I'm sure you know why I've called you here today," said Edgar, a curmudgeonly old
coot.
"Yes," answered Edith, thinking that Edgar would finally grant the monastery a much needed donation. After all, he had no family, and obviously no friends, so he might as well grant a portion of his vast fortune to her church, which had fallen on hard times.
"Well, the rest is just business then. Shall we go for a stroll among the gardenias and discuss it?" asked Edgar.
"Yes, I do so adore gardenias," answered Edith, humoring the man until he bequeathed his
fortune to the church that had been soliciting him for so long.

During their stroll, Edgar and Edith chatted congenially, both of them waiting for the right moment to bring up their respective thoughts.
When they reached the edge of a cliff that lay at the edge of Edgar's enormous estate, they stopped to begin their conversation.

"As you know," began Edgar, "I have been diligently conserving my resources in order to use them to their best affect."
"Indeed," interrupted Edith, "and the brothers and sisters at the monastery would certainly bless you in their prayers and feel undying gratitude if you took upon yourself to fund our missionary ventures."
"Yes," answered Edgar, "but I have been thinking that my resources could be used to produce a much more drastic and immediate effect if I transferred them to you." And with that, Edgar proceeded to transfer his energy to Edith in a most drastic manner, by pushing her off of the cliff.

intial energy = final energy, or PEga+W=PEgb+KEb
