Work Energy And Power Formulas List

The list of formulas will help students to revise all the important notes quickly before the main entrance exams.

Work energy and power formulas list.

Joule the units of work equivalent to a newton meter. 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. Work done is generally referred in relation to the force applied while energy is used in reference to other factors such as heat. H m is the mass g is the gravitational acceleration and h is the distance potential energy of the spring.

Work power and energy formulas. Below students will find a compilation of all the formulas related to the topic of work energy and power. In older works power is sometimes called activity. The work energy principles discussed here are identical to electric work energy principles.

The output power of a motor is the product of the torque that the motor generates and the angular velocity of its output shaft. In the international system of units the unit of power is the watt equal to one joule per second. Power work done per unit time. Before moving to physics.

Work done by. Also units of energy. In physics power is the amount of energy transferred or converted per unit time. Work a force applied over a distance.

Power is a scalar quantity. W fs cos ө. X k is the spring constant and x is the amount of compression or streching kinetic energy. Ek 1 2mv m is the mass v is the velocity work power energy exams and solutions.

See definition of total mechanical energy. Work formula example of work types of energy power formula questions. In this article we will learn all about the concept of work power and energy. 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.

It is a scalar quantity. 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. Power is defined as work done per unit time.
