WebbPower is the rate of work - the amount of work done, or energy produced, over a unit of time. It is measured in watts (symbol W). One watt is equal to one joule divided by one second, i.e. one joule per second. Efficiency is the ratio between useful work done and the energy expended. It usually expressed as a percentage.

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. K E = 1 2 m v 2. WebbEfficiency is the often measurable ability to avoid wasting materials, energy, efforts, money, and time while performing a task.In a more general sense, it is the ability to do things well, successfully, and without waste. In more mathematical or scientific terms, it signifies the level of performance that uses the least amount of inputs to achieve the … instagram affiliate offersWebbAs stated above, work is the product of force and distance, and power is work per unit of time. Consequently, if a 33,000-lb weight is lifted through a vertical distance of 1 foot in 1 minute, the power expended is 33,000 ft-lb per minute, or exactly 1 hp. Work is performed not only when a force is applied for lifting; force may be applied in any direction. jevington way se12

"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 ... " - The power expended without doing useful work
