  2. Physicists like to the use energy unit called the joule (named after James Joule) because it makes their equations look simpler. There are about 4000 joules in a Calorie, 3600 in a Wh, 3.6 million in a kWh. The energy table below shows the approximate energies in various substances.

  3. •It turns out that energy possesses a fundamental characteristic which makes it very useful for solving problems in physics: **Energy is ALWAYS conserved** Kinetic energy K is energy associated with the state of motion of an object. The faster an object moves, the greater its kinetic energy. Potential energy U represents stored energy, e.g., in a

  4. Power (P) is the rate of energy transfer (energy transferred per unit tim e). As work is a measure of energy transfer, the rate of doing work = the rate of energy transfer , therefore:

    In physics, power (symbol: P) is the amount of work done per unit of time. Definition. This can be modeled as an energy flow, equivalent to the rate of change of the energy in a system, or the time rate of doing work, where. is power. is energy.

  7. Chapter 1: Energy, Work, and Power. Energy is a very important concept both in physics and in our world at large. Energy takes various forms.
