Energy: The Importance Of Energy In The World

We humans use energy in our everyday lives without energy there’s to life. Without energy how will we able to use transportation? Nobody wants to walk to work or to school that would be a major crisis. Energy is very important to the earth’s society. The energy from the sun gives us sunshine so we can see. When we eat energy been here for centuries, the word energy even sounds powerful, energy is one of the most powerful things in the world. Energy is the ability to do things such as playing, running, jogging, or dancing, in other words just being active. This world is made up of energy too. Energy consists of a few properties that are very important. Energy can’t be created and it can’t be destroyed. Energy can go from one place to another. Two most basic forms of energy are kinetic energy and potential energy.

Kinetic energy is energy in motion. Any moving object has kinetic energy. If you rub your hands together fast and you start to feel the heat that’s a great example of kinetic energy. There are many examples of kinetic energy like throwing a ball, jumping rope, running, playing sports. Forms of kinetic energy are thermal energy, sound energy, electric energy, and radiant energy.

The word thermal in thermal energy means heat and temperature, so all together means heat that comes from energy. Conduction, convection, and radiation are the types of thermal energy. Conduction is when two molecules collide. An example of conduction is a pot on a stove with boiling water. Convection is heat transferred to another object. An example of convection is a pot on a stove with boiling water and bubbles forming. Radiation is energy from the sun. A man standing outside in the sun and the sun rays are hitting the man and he start to sweat.

...n. When the sun goes down, solar radiation is at zero. Solar radiation is used in everyday life. There are three kinds of solar radiation. One type of solar radiation is Ultraviolet radiation. Ultraviolet Radiation is the wave we’re not able to see. Unlike the visible light, the visible light helps us see the waves. They have the colors of the rainbow. Another kind of solar radiation is Infrared Radiation. Infrared Radiation is wave that are given off by many warm things and create heat in all things they strike.

Potential energy is the energy callable too position. For example if I had an object that is attached too a as string and you hold it at one side and don’t let it go it has the quantity of potential energy and if you let it go to swing back and forth that energy is changed from potential energy to kinetic energy. Potential energy is used in many ways.
