Work Energy And Power Formulas List

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 energy and power formulas list.

Power is a scalar quantity. Ek 1 2mv m is the mass v is the velocity work power energy exams and solutions. Work a force applied over a distance. The work energy principles discussed here are identical to electric work energy principles.

In the international system of units the unit of power is the watt equal to one joule per second. 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. 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.

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

Joule the units of work equivalent to a newton meter. W fs cos ө. In physics power is the amount of energy transferred or converted per unit time. Power work done per unit time.

The list of formulas will help students to revise all the important notes quickly before the main entrance exams. See definition of total mechanical energy. In older works power is sometimes called activity. In this article we will learn all about the concept of work power and energy.

The output power of a motor is the product of the torque that the motor generates and the angular velocity of its output shaft. 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. X k is the spring constant and x is the amount of compression or streching kinetic energy. Work done by constant force.

Before moving to physics. Work done by. Also units of energy.
