An object possessing mechanical energy can do work by applying force. The change in mechanical energy is the work done. For example, when a bow is pulled, it stores energy. When released, the bow uses its stored energy and pushes the arrow to its trajectory. Thus, the bow works on the arrow at the expense of its mechanical energy.

The mechanical energy of a bowling ball gives the ball the ability to apply a force to a bowling pin in order to cause it to be displaced. Because the massive ball has mechanical energy (in the form of kinetic energy), it is able to do work on the pin. Mechanical energy is the ability to do work. A dart gun is still another example of how ...
where P is the absolute pressure of the gas, V its volume, n the number of moles, R the gas constant, and T the absolute temperature. The value of R is 8.314 J mol −1 K −1, or 0.082 l atm K −1 mol −1 ing this latter value, the volume of a mole of gas can be readily found to be 22.4 l at 273 K or 0 °C. For a constant volume, such as that of a bicycle tire, the pressure is ...
