Physics 2010 and 2020 constitute a terminal course sequence covering the principles of mechanics, heat, electricity and magnetism, optics, atomic, solid state, nuclear, and particle physics. A working knowledge of arithmetic, elementary algebra, and trigonometry is essential. The PHYS 2010 - 2020 sequence does not normally serve as prerequisite for the courses numbered 3110 and above. Students who plan to take more physics should take PHYS 1610, 1620, 2610, 2620, or PHYS 2310, 2320, 2620. PHYS 2010, 2020, in conjunction with the laboratory PHYS 2030, 2040 satisfies the physics requirement of medical and dental schools. PHYS 2010 is prerequisite for 2020. Three lecture hours.
