Work Energy And Power Formulas List

Work a force applied over a distance.

Work energy and power formulas list.

These list of physic formula of class 11 chapter work energy power is useful and highly recommended for quick revision and final recap of chapter work energy power. The list of formulas will help students to revise all the important notes quickly before the main entrance exams. The output power of a motor is the product of the torque that the motor generates and the angular velocity of its output shaft. Work done is generally referred in relation to the force applied while energy is used in reference to other factors such as heat.

Work done by. These formulas show that work is the energy associated with the action of a force so work subsequently possesses the physical dimensions and units of energy. In older works power is sometimes called activity. Below students will find a compilation of all the formulas related to the topic of work energy and power.

In this article we will learn all about the concept of work power and energy. In the international system of units the unit of power is the watt equal to one joule per second. Work done by constant force. Academic team of entrancei prepared short notes and all important physics formulas and bullet points of chapter work energy power class 11 physics.

W fs cos ө. Also units of energy. Before moving to physics. Work power and energy formulas.

H m is the mass g is the gravitational acceleration and h is the distance potential energy of the spring. Power is defined as work done per unit time. Work formula example of work types of energy power formula questions. Power work done per unit time.

It is a scalar quantity. See definition of total mechanical energy. Ek 1 2mv m is the mass v is the velocity work power energy exams and solutions. In physics power is the amount of energy transferred or converted per unit time.

The work energy principles discussed here are identical to electric work energy principles. X k is the spring constant and x is the amount of compression or streching kinetic energy. For formulas see work done by a constant force parallel to displacement and work done by any constant force and work done by a position dependent force.
