  2. Power (physics) - Wikipedia

    en.wikipedia.org/wiki/Power_(physics)

    Power is the rate with respect to time at which work is done; it is the time derivative of work: =, where P is power, W is work, and t is time. We will now show that the mechanical power generated by a force F on a body moving at the velocity v can be expressed as the product: P = d W d t = F ⋅ v {\displaystyle P={\frac {dW}{dt}}=\mathbf {F ...

  3. Work (electric field) - Wikipedia

    en.wikipedia.org/wiki/Work_(electric_field)

    The work can be done, for example, by generators, (electrochemical cells) or thermocouples generating an electromotive force. Electric field work is formally equivalent to work by other force fields in physics, [1] and the formalism for electrical work is identical to that of mechanical work.

  4. Work (physics) - Wikipedia

    en.wikipedia.org/wiki/Work_(physics)

    The ancient Greek understanding of physics was limited to the statics of simple machines (the balance of forces), and did not include dynamics or the concept of work. During the Renaissance the dynamics of the Mechanical Powers, as the simple machines were called, began to be studied from the standpoint of how far they could lift a load, in addition to the force they could apply, leading ...

    With this low power consumption came the possibility of using solar cells as the power source, realised around 1978 by calculators such as the Royal Solar 1, Sharp EL-8026, and Teal Photon. The interior of a Casio fx-20 scientific calculator from the mid-1970s, using a VFD.

  6. Watt - Wikipedia

    en.wikipedia.org/wiki/Watt

    Mass times acceleration due to gravity times height divided by the time it takes to lift the object to the given height gives the rate of doing work or power. [i] A laborer over the course of an eight-hour day can sustain an average output of about 75 watts; higher power levels can be achieved for short intervals and by athletes. [4]
