The discussion centers on the AS Physics course, specifically focusing on base units, base quantities, derived units, and derived quantities. Key examples include base units such as distance, time, mass, and charge, with derived units like force (mass x distance/second²) and energy (mass x distance²/second²). Understanding these concepts is crucial for grasping the underlying physics principles. The conversation emphasizes the importance of foundational knowledge before delving into complex unit relationships.
PREREQUISITESThis discussion is beneficial for AS Physics students, educators seeking to explain unit concepts, and anyone looking to strengthen their understanding of physical quantities and their relationships.
Base units are units of distance, time, mass, charge. Units for other quantities, such as Force and energy, are derived from these units (Force is in units of mass x distance/ sec^2 for example; energy is mass x distance^2/sec^2). You won't understand why the units are this way until you understand the underlying physics. Don't worry about it for now.ben-Newton said:I have just started the AS Physics course and we have been doing base units, base quanntities, derived units and drived quantities. This stuff completely baffles me, and cannot find a site which explains this stuff in bog standard english. Please could someone help me.
