Document Summary

These units are based on seven basic units, being: Many other units can be derived from any of these seven basic units: Force: newton (n: one newton is the force required to accelerate a mass of one kilogram at a rate of one meter per second per second. Energy: joule (j: one joule is the energy expended by a force of one newton acting through a distance of one meter. Magnitudes are expressed using base-10 notations, with scientific and engineering notation used in this course. Scientific notation: one whole number digit in mantissa. Engineering notation: exponent is a multiple of 3, mantissa in the range of [1. 0 1000. 0] Si unit for the charge of an object is the coulomb (c) Symbol q or q is used for charge. Nucleus (includes protons and neutrons) surrounded by orbiting electrons. Electrons have negative charge, protons have positive, neutrons have no charge (uncharged) atoms have equal number of protons and electrons.
