Urgent Help Required

  1. Sep 5, 2006 #1
    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.

    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.
