Document Summary
Physics: involves the study of the physical world in parcular the properes and interacons of maer and energy and their relaonship. Energy: ability of maer or radiaon to do work. Forms of energy include heat, electromagnec (light), kinec (moon), potenal and nuclear (core pf the atom). The fundamental quanty used to describe physical quanes are called dimensions. For example length, mass and me are all dimensions. Dimensional analysis: a process whereby an equaon can be checked. The number is wrien with one number to the le/ of the decimal point and appropriate power of 10. Signi5cant 5gures are a re6econ of the precision of a measurement or quantave value. Science si system (most common): uses a set of base and derived units to measure the physical world. The four types of moon include straight-line moon, circular moon, projecle moon and rotaonal moon.
