Energy – a quantity associated with an object that relates to its speed or position in space, relative to another object. A force is required to change the energy of an object
Work (J) – the product of force moving through a displacement in the same direction as the force.
Internal Energy – the sum of all the microscopic kinetic and potential energies of all molecules in a substance. On the microscopic scale there is a lot of random motion (Brownian Motion).
Work Done By A Gas – gas is expanding
Work Done On a Gas – gas is contracting
Conservation of Energy – energy cannot be created or destroyed only transformed from one form to
