# What Is Work? # What Is Work?

Work is the transfer of energy from one object to another via a force or displacement. The product of force and displacement is often used to describe work. It is also called mechanical energy, or work. The following discussion will discuss some of the basic properties of work. Let’s first examine some of its most common forms. The first two types of work are mechanical and electrical. The second type of physical energy is thermal energy. These forms of heat and electricity are largely derived from geothermal sources.

A force performs work on an object when it causes an object to move. This work is proportional to the direction of displacement relative to the force. If the force is negative, the object experiences zero work. For example, if a coolie lifts a mass on his head at a 90-degree angle, the mass is experiencing zero work. The second type of mechanical energy is electrical energy. It is generated by moving a source of energy in the form of a current or a magnetic field.

The third type of mechanical energy is thermal energy. The amount of heat that is created by a heating element is known as radiant energy. A thermal energy source is used to create a heated environment. Unlike heat, radiation, or light, thermal energy is free and can be collected from any surface in the world. If a person’s body temperature is above freezing, he will sweat, causing him to lose his cool. A second type of physical energy is thermal. This form of thermal energy will heat up the surrounding environment.

Lastly, there is non-SI units of work. These include newton-metre, erg, foot-pound, liter-atmosphere, and horsepower-hour. These are also used to measure different types of energy. A kilogram of water is one newton. That is why 10 kg of pressure is equal to 20 newtons. Then, the equivalent of a kilogram is one kilowatt-hour.

Work is energy transferred from an object. The amount of energy that is transferred is called work. It is the process of transferring energy from an object to another. When a force acts on an object, it can cause it to move and create an additional amount of energy. This is referred to as positive work. By contrast, negative works take energy from an object. The latter is a form of negative work. This kind of energy is transferred from one body to another.

Another unit of work is energy. It is the force times the displacement. Similarly, a baseball player will throw a ball at a baseball with a force of ten to twenty Newtons. The total amount of work is the joule. A joule is equivalent to a kilogram of energy. A joule is measured in newton-meters. A kilowatt-hour is the energy of an apple.
