Work Energy And Power Formulas List

Ek 1 2mv m is the mass v is the velocity work power energy exams and solutions.

Work energy and power formulas list.

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. In physics power is the amount of energy transferred or converted per unit time. 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.

Work done by constant force. 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. Also units of energy.

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. Academic team of entrancei prepared short notes and all important physics formulas and bullet points of chapter work energy power class 11 physics.

Power work done per unit time. See definition of total mechanical 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. Before moving to physics.

It is a scalar quantity. Joule the units of work equivalent to a newton meter. Work a force applied over a distance. 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. Work power and energy formulas. Work done is generally referred in relation to the force applied while energy is used in reference to other factors such as heat. The work energy principles discussed here are identical to electric work energy principles.

Work formula example of work types of energy power formula questions. 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.
