WebbClosely associated with energy is the concept of work. Energy is transferred to another system when you do work. Power provides a measure of the energy expended per unit time. Efficiency of machines provides a measure of the energy converted into useful work. This module is about work, power, and energy. It consists of the following lessons:

WebbPower is defined as the rate of doing work, or the limit of the average power for time intervals approaching zero, P = dW dt. P = d W d t. If the power is constant over a time interval, the average power for that interval equals the instantaneous power, and the work done by the agent supplying the power is W = P Δt W = P Δ t. WebbIf you hold it over your head, it is not changing distance, and thus you are not performing work.

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. inclination\u0027s xuWebbNow you are doing work and this takes energy. If you keep this up for a very long distance, you would probably get winded. If your friend lets you move very fast and you still pull with the same force, you will get very winded. When you just pull without moving, you are exerting a force but you aren't doing work so you probably won't get tired. incoterms coverWebbIf we take away the useful labour expended upon them, a material substratum is always left, which is furnished by Nature without the help of man.
