Work Energy And Power Formulas List

Power is a scalar quantity.

Work energy and power formulas list. Ek 1 2mv m is the mass v is the velocity work power energy exams and solutions. Work done is generally referred in relation to the force applied while energy is used in reference to other factors such as heat. It is a scalar quantity. In this article we will learn all about the concept of work power and energy.

Joule the units of work equivalent to a newton meter. Work a force applied over a distance. Work formula example of work types of energy power formula questions. X k is the spring constant and x is the amount of compression or streching kinetic energy.

The work energy principles discussed here are identical to electric work energy principles. Work power and energy formulas. Also units of energy. 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.

Power is defined as work done per unit time. W fs cos ө. Power work done per unit time. Academic team of entrancei prepared short notes and all important physics formulas and bullet points of chapter work energy power class 11 physics.

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. Work done by. 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. This formula for force can be substituted in to the formula for work w fd therefore the work done by the force on an object is equal to the change in the object s kinetic energy w k 2 k 1 w δk in this formula the greek uppercase letter δ delta is used to mean the change in.

Below students will find a compilation of all the formulas related to the topic of work energy and power. In the international system of units the unit of power is the watt equal to one joule per second. H m is the mass g is the gravitational acceleration and h is the distance potential energy of the spring. Work done by constant force.

In physics power is the amount of energy transferred or converted per unit time. The output power of a motor is the product of the torque that the motor generates and the angular velocity of its output shaft. The list of formulas will help students to revise all the important notes quickly before the main entrance exams.
