Kinetic Energy

Author's Note:
This is an essay on Kinetic energy and what it is used for, how to create it, and what it is. I am using a report type voice and am focusing on word choice.

Zipping down a drop almost fifty feet tall, gliding through the air, and slicing through the turns. The person sitting next to you is screaming all the way down the hill. You're buckled up, but still scared you might fall off because it is moving so quickly. Remembering that all of your friends are riding with you makes you feel safe. The power that this machine would need, would have to be a very great amount. Once you get off, you turn around to look at it one last time, it was a roller coaster. A roller coaster is just one object that posses kinetic energy.

Kinetic energy is the energy of motion, seen as the movement of an object, particle, or set of particles. Any object in motion is using kinetic energy. For example, a person walking, a thrown baseball, even a crumb falling from a table. Objects that are not in motion possess potential energy, the other main type of energy. Basically, if it's moving, it obtains Kinetic energy.

Moving objects are everywhere, but there are some obvious examples, such as roller coasters, dribbling a basketball, or moving car. There are also a number less obvious objects such as walking, kicking, or jumping. Anything can have Kinetic energy whether it is a machine, an object, or a person. Big or small, they all use Kinetic energy.

Kinetic energy is, in my opinion, the most interesting kind of energy to learn about. Being able to understand how it is used, what it's used for, and more. Riding a bike or dribbling a basketball is all that needs to happen to obtain Kinetic energy. It can be found in a roller coaster or a falling piece of bread. Overall, Kinetic energy is the energy of a moving object.
