![]() ![]() The electromagnetic radiation produces light as a form. Sometimes chemical combustion or nuclear fission can also help heat engines to function. These heat engines run on the kinetic energy of water and wind. These generators use heat engines to function. Electromechanical generators are responsible for generating electricity at power stations. ![]() When kinetic energy produces energy, it becomes electrical energy. Photosynthesis is a classic example of a chemical reaction in which solar energy converts to chemical energy. The bonding and diffusing of chemical bonds of different elements is an example of this.Ī chemical reaction has the capability to transform any chemical substance into any form of energy. When any chemical substance goes under transformation by a chemical reaction and transforms another chemical substance, there is the production of chemical energy. The SI unit of energy is joule or J which is the same as work done. Thus the work done capacity measures the energy. In the case of work done, object working loses energy while work done on an object gains energy.Īnd the object with energy can exert force on another object to transfer energy. The energy converts to form but it’s not created or destroyed.Īn example is the production of electric energy from solar energy. W = m x g x h ( W – work done, m – object mass, g – gravity acceleration, and h – height of object lift ) Energy The formula for work done against the gravity is – The work done against gravity is equal to the lifting height of the object and the product of the weight. And when the object moves in the same direction as force direction, the work done is positive. When displacement is perpendicular to the force direction, work done is zero as the force applied is zero. When an object moves opposite to the force direction like friction by an object moving forward, the work done is negative by friction. This depends on the displacement direction of an object. The work done by the force on an object is of three types – positive, negative, and zero. The Angle between the Force Vector and the Displacement Vector ![]() If the displacement is zero in a direction, force acting becomes zero, and thus work done is zero as well. In the case of zero force on an object, the work done becomes zero.ĭisplacement refers to the shortest distance covered by an object from start to end position. It is a vector quantity and focuses on direction and magnitude both. Work done = Force x Displacement or W = F x s Factors Affecting Workįorce is a physical pull or push that leads to a change in an object’s velocity and acceleration. The SI unit of work is Joule or J and denotes it in all the formulas. Work looks at the idea of the magnitude, not direction. The magnitude of the force applied divided by the distance moved in the force direction gives us work done by force. Work is a situation when there is a displacement of an object from point A to point B by an applied force. Gaspard-Gustave Coriolis was the mathematician behind the discovery of concept work. Some elements that we’ll see in the article below are – definition, formula, derivation, application, and much more. In this article, we will look at basic physics concepts like Force, Displacement, Forms of energy, the law of energy conservation, and many other important physics concepts. This is mainly due to energy’s presence for doing work. Especially work and energy are working side by side almost all the time. They are part of the basic physics module and are important to build an understanding of the subject.Īll three concepts are correlated and have common elements and an impact on each other. ![]() Work, Energy, and Power are important physics concepts.
