Kinetic, potential, thermal, chemical, electrical, electrochemical, electromagnetic and nuclear energy are the different forms of energy. Each energy form measures the ability of an object to do work on another object. Each energy form is a way that an object possesses energy.Continue Reading
Kinetic energy refers to an object or system in motion. For example, a ball flying through the air possesses kinetic energy. Potential energy is an object's potential to turn into kinetic energy. A book sitting on a table has potential energy because it could fall off the table. Thermal energy is related to the temperature of a system. The higher temperature results in an increase in potential and kinetic energy.
Chemical energy is a form of microscopic potential energy. For example, glucose reacting with oxygen releases energy. Electrical energy produces electric currents that can be transferred from one system to another. Electrochemical energy is electric energy that can be stored in a chemical way. A car battery is an example of an electrochemical energy source. Electromagnetic energy is light energy. The sun transmits light to the Earth through radiation. Nuclear energy is a source of energy that involves a change in the structure of the nuclei of atoms.Learn more about Motion & Mechanics
In chemistry, equilibrium is a state in which both the products and reactants in a chemical reaction have no tendency to change over time. This does not mean that the chemical reaction has stopped, but that the formation of substances has reached a stable, or balanced, condition.Full Answer >
Gravity is a force that attracts matter to other forms or matter; it is a very weak force. It is the weakest of the fundamental forces, according to scientists. It is even weaker than what is called the weak force.Full Answer >
Laminar and turbulent flows are the two major forms of fluid flow, with laminar flow being an orderly flow with all the fluid molecules moving parallel in the direction of flow, whereas in turbulent flow, different streams of fluid form eddies and unpredictable currents in a different direction than the overall direction of flow. Which type of flow arises in a fluid depends on its speed relative to its viscosity and the size and shape of the pipe or other channel carrying the fluid. Viscosity is the resistance to flow, and more inherently viscous fluids are more resistant to turbulence.Full Answer >
Water moves through Earth's surface and atmosphere through the hydrologic cycle and changes through three distinct forms, which are as a solid, liquid and gas. This cycle allows water to move through the atmosphere by becoming a gas before being redistributed through precipitation.Full Answer >
