Unformatted text preview: Physics 1C Lecture 12A Chapter in book Typically more than One lecture per chapter Pdf of Lectures are available on web, so you can download ahead of time. Information (I) 3 lectures per week, Mo/We/Fri 4-4:50pm except for the 4 quizzes which are during normal lecture time on: Monday April 11th Friday April 22nd Monday May 9th Friday May 20th One session where TA discusses HW Thursday 3-6pm (location as yet unknown) Information (II) There is a web site with: Lectures available before class Suggested optional Homework Grades for quizzes Contact info for fkw and Nick Keller (TA) What else do you want to know? Mass on a Spring Lets say we have a mass hanging from a spring. What would a force diagram look like for the mass in this situation? mass F gravity, Earth on mass F pull, spring on mass F y = 0 a y = 0 The spring pulls up on the mass -> net force is zero -> no acceleration -> static equilibrium. Mass on a Spring But what would happen if we added another mass to the bottom of the system? The spring stretches further We have added more force of gravity and the spring added more force by displacing it more from its equilibrium position. If we measured displacement vs mass attached, wed Fnd a linear relationship. Mass on a Spring This pull force from the spring (also known as a restoring force, F spring ) will resist either a compression or a stretching....
