  • The rate of energy conversion or transmission (i.e. power) is related to the physical quantities such as force, speed, voltage, current, etc.For mechanical system, rate of energy transfer (i.e., power) to an object is the product of the force (F in Newton) and the speed (S in meter/sec) of the point where the force is applied.Q1. A person pushes an out-of-gas car with a force of 100 Newton (about 22.5 lb of force) to maintain a speed of 0.2 m/s. It took him 10 minutes to get to the nearest gas station. How much energy did this person use to do this work?...

  • Laws designed to prevent usury, or the taking of "excessive" interest, have long been the subject of controversy.
