Each student should bring to the laboratory a physics laboratory notebook (coil-bound with ¼" or 5 mm grid paper), an inexpensive set of geometrical instruments and a calculator with trigonometric functions.
Objective: To understand how to report both a measurement and its uncertainty. Learn how to propagate uncertainties through calculations. Define, absolute and relative uncertainty, mean, standard deviation, and standard deviation of the mean. Equipment: meter stick, 1 kg mass, ruler, caliper, short wooden plank.
The objective of this course is to teach electricity and magnetism (E&M) by observations from experiments. This approach complements the classroom experience of Physics 1B,C where you learn the material from lectures and books designed to teach problem solving skills.
The experiments described in this manual are designed to accompany Physics 250. They are for the most part different in character from those done in conjunction with Physics 150-151. In those courses you studied macroscopic physics such as falling bodies and magnetic fields
Problem 1: Calculate the time of fall of a droplet (z=0.1 cm) which, if it carries a charge of 1e, can be held stationary with a voltage of 200 Volts. Problem 2: Describe another completely independent method for determining the value of the electron charge. You can obtain results of impressive accuracy in this experiment provided you take care
Objective: To understand how to report both a measurement and its uncertainty. Learn how to propagate uncertainties through calculations. Define, absolute and relative uncertainty, standard deviation, and standard deviation of the mean. Equipment: meter stick, 1 kg mass, ruler, caliper, short wooden plank.
The goals of the lab are twofold: (1) for you to see and experience physics at a hands-on level and (2) for you to learn how to use the experimental method to reach conclusions.
