Physics In Our Everyday Life

Physics is not something that only knowledgeable scientist think about because physics coincides with our everyday life. They consist of energy, kinetic energy, potential energy, conservation of energy, velocity, acceleration, mass, force, and gravity.

Fist there is energy. You need to go to bed early so you will have energy in the morning to go to school. Energy gives you the e ability to do work. Energy is everywhere in nature, sunlight wind, water, plants, and animals. We use energy everyday. There are two kinds or energy. There's kinetic energy and potential energy. There are many forms of energy there's 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. The total energy of an object never changes.

Then there's kinetic energy. There are many types of energy, but one of the most interesting types of energy is kinetic. Kinetic energy is the energy of motion. When an object is in motion, even in a vertical or horizontal motion, it has kinetic energy. There are three types of kinetic energy; rotational, vibrational, and transnational. To find kinetic energy in an equation, you will need the mass and speed of the object. Usually potential energy is turned into kinetic energy. When a cart is on top of a hill, it is full of potential energy. As soon as it starts going down the hill it starts gaining kinetic energy.

After comes potential energy and force. Potential energy can store energy as the result of its position. Potential energy exists whenever an object that has, mass a position within a force field. The most everyday example of this is the position of objects in the earth's gravitational field. The potential energy of an object in this case is given by the relation PE=mgh.

Force is any influence that...
