Energy (Mechanical)

Hello people,,,

Today I am going to talk about Kinetic Energy and Potential Energy.

First, what is energy? Energy is the ability to cause change.

So, what is kinetic energy and potential energy? You will be surprised if you learn what it is, because it is so near to you.

To make it clear, I will tell you the definition first. Kinetic energy is the energy an object has due to its motion. If object isn’t moving, there is no kinetic energy, and Potential energy is the energy stored in an object because of its position.

It is hard to understand with these definitions, right? Okay. I will give you the examples. Let’s say there is a person on the bungee jumping. If a person is at the highest place, which is the place you jump, it means a person has most potential energy. When a person falls, the person will gradually get a kinetic energy. When a person reaches the bottom, the ground, it means a person has the most kinetic energy. When a person weights more, a person has more potential energy. If I say it easier, potential energy depends on its mass and height

Different with potential energy, kinetic energy depends on mass and speed. When the person weighs more, and when speed is faster, person has more kinetic energy than lighter person.

 

Energy can be transferred and stored. Energy gets transferred when objects collide. I will make an example with bowling. When the bowling ball gains energy by a person who throws the ball, and when it rolls, it has kinetic energy. When the ball collides with the bowling pins, pins are gaining the energy. Since the pins don’t have wheels, it knocks out. Additionally, energy can never be destroy or created. It just looks like they do, but they are only changing the forms of the energy like potential and kinetic.

I got definitions by the textbook physics!

I hope you understood!
