Air resistance is a force that acts on objects when they move through the AIR. It is caused by the friction between the object and the AIR molecules. DRAG is a type of AIR resistance that is created when an object moves through a fluid, such as AIR or water. Ohm is the unit of electrical resistance, which is a measure of how difficult it is for electricity to flow through a material. Ohmage is the total resistance of a circuit, which is calculated by adding up all the individual resistances in the circuit. Ohms is the plural form of ohm. Aero is a prefix meaning 'AIR' or 'ATMOSPHERE'. OMEGA is the last letter of the Greek alphabet and is often used to represent the end of something.
