The power expended without doing useful work

WebbWhen force was applied to a body and visible displacements can be seen or measured they say that work was done. Then the formula for work is applied and solving for its amount … WebbIn physics, power is the rate of doing work. It is the amount of energy consumed per unit time. The unit of power is the joule per second (J/s), known as the watt (in honor of James Watt, the eighteenth-century developer of the steam engine). For example, the rate at which a lightbulb transforms electrical energy into heat and light is measured ...

Webbf = w = m g. The work we do on the rock equals the force we exert multiplied by the distance, d, that we lift the rock. The work we do on the rock also equals the rock’s gain in gravitational potential energy, PEe. W = P E e = f m g. Kinetic energy depends on the mass of an object and its velocity, v.
