What is work power and energy definition?
Work is referred to as the displacement of an object when a force (push or pull) is applied to it while energy is referred to as the capacity to do the work. It exists in various forms like potential, kinetic, chemical, thermal, nuclear, electrical energy and so on. Power is the work done per unit of time.
What is power class 9th?
Power of a body is defined as the rate of doing work by the body. unit of power is joule per second that is nothing but watt (W).
What is relationship of work energy and power?
Force exerted on an object over a distance does work. Work can increase energy, and energy can do work. Power is the rate at which work is done.
What is Work energy and power with example?
Work is the application of a force over a distance. Lifting a weight from the ground and putting it on a shelf is a good example of work. The force is equal to the weight of the object, and the distance is equal to the height of the shelf (W= Fxd). The energy of a moving object is called kinetic energy.
Which is the best definition of power?
Power is defined as the ability to act or have influence over others. An example of power is the strength needed to run five miles. The definition of power is operating electrically or having strength or force.
What is power explain?
In physics, power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. In older works, power is sometimes called activity. Power is a scalar quantity.
What do you mean by energy?
energy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. After it has been transferred, energy is always designated according to its nature.
What is difference work and power?
Work is defined as the process of energy transfer to the motion of an object through the application of force. Power is defined as the amount of energy transferred in unit time. The SI unit of power is the watt.
What is the importance of work power and energy?
Work, Power and Energy is a very important concept in physics. Work done by all the forces is equal to the change in kinetic energy.
How do you define power in terms of energy?
In physics, power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. Power is a scalar quantity.
What is power definition simple?
Power is defined as the ability to act or have influence over others. An example of power is the strength needed to run five miles. An example of power is the authority a local government has to collect taxes. The definition of power is operating electrically or having strength or force.
