Physics in Everyday Life

Just about everything you do from moving to eating to listening to music involves physics. Now that I have really explored them I think it is hard to go about our day and not do something that involves physics. Some of the things I will talk about are getting out of bed, the eye and how eye glasses help a person see better, speakers, the Frisbee, sailing, and the pulleys I use to get my jeep unstuck in the mud when I ride in the woods. All of these require energy, and energy is what physics is all about. There is kinetic energy, potential energy, conservation of energy, velocity, acceleration, mass, force, and gravity. Energy gives you the ability to do work. Energy is everywhere in nature and in life, we use energy every day. There are many forms of energy; light, chemical, mechanical, heat, electric, automatic, and sound. All these forms of energy can be broken down either into kinetic energy or potential energy. The law of conservation of energy is that energy can neither be created nor destroyed. One thing that is hard for most twenty-one year olds is to get out of bed early. Now I know that physics is partly to blame for this! When I am just lying in bed I am full of potential energy, and when I over come inertia I change that potential energy in to kinetic energy and I have acceleration and direction. Inertia is in Newton's first law of physics. It states that a body at rest will remain at rest until acted upon by an external force. Besides inertia I have the force of gravity pushing me down into the mattress, and the mattress pushing up against me so I do not fall through. This makes me balanced and at rest. So to get out of bed each day I have to overcome inertia. After you get out of bed you have to walk somewhere, walking is the basic mode of transportation that humans use to move, meaning that we do not move by hopping or something like that. All the laws of basic physics are involved in
