Document Summary
Energy: this is the ability to do something. It moves matter or changes its condition in some manner. Matter: this is anything that has mass and occupies space. Work: this is done when matter is pushed, pulled, or lifted over some distance. Work= force applied x distance the force is applied for. Work is measured in joules (so is energy). Heat: this is the energy that is transferred form one object to another when a temperature difference exists between the two objects. Heat can move by conduction, convection, radiation or advection. Heat flux density: the rate of energy flow over one square meter. It can only change from one form to another. This is also known as the first law of thermodynamics. The total amount of energy in an object determines the amount of work the object can so. Energy has two main forms potential energy and kinetic energy.
