Essay On Kinetic Energy

921 Words4 Pages
Anything that has motion involved is kinetic energy. The motion can be able to produce kinetic energy. An object that is moving can be able to do work with anything it hits. The conclusion of its motion is the amount of work being done. Kinetic energy can be passed from one object to another by clashing towards each other. Kinetic energy is a scalar quantity, and also described by magnitude. This type of energy depends not only on its motion but also on its mass. If you double the mass of an object, you double the kinetic energy. The kinetic energy from a moving object is the same as the work that it does while it is being brought to a rest. Forms of kinetic energy are: vibrational, rotational, and translational. An equation that is used to represent the kinetic energy (KE) of an object: KE = 0.5 • m • v2. The standard unit for kinetic energy is the joule (J). The joule is the standard unit for energy in general. If you were to double the speed…show more content…
For example, as a roller coaster goes downhill it builds kinetic energy. Potential energy is energy of an object that does not move at all. Think of a book on top of a table, it doesn’t move at all. Another example is a roller coaster on the top part of the hill before it goes down. The potential energy is converted into kinetic energy once it falls downhill. In thermal energy or heat energy is how fast the particles of something are moving. The more temperature you have, the more thermal energy you have which means the particles will be much faster. A hot cup of coffee has lots of thermal energy unlike a cold beverage. In chemical energy, think ability of your body to do work. The glucose in your body is said to have "chemical energy" because the glucose releases energy when chemically reacted with oxygen. Your muscles use this energy to generate mechanical force and also heat. These parts get rearranged in chemical reactions, releasing or adding to this potential
