Basic Idea:

• Measure the spring constant, k, of an SHO, and use it to predict it's period.

	What:	How Many:	Where:
	Pasco Dynamics Track	1	non-Majors storeroom, shelves J0 & JJ0      (look up!)
	Pasco Collision Cart (w/o plunger - see below)	1	non-Majors storeroom, shelf F4
	Springs	2	non-Majors storeroom, shelf F4
	Small screws	2	non-Majors storeroom, shelf F4
	Small Masses with built-in hook (See below)	10g (1) 20g (2) 50g (1)	non-Majors storeroom, shelf D2
	500g Mass Block (black)	1	non-Majors storeroom, shelf F4
	String with small hook	1	non-Majors storeroom, shelf F4
	Super Pulley	1	non-Majors storeroom, shelf F4
	Bubble level	1	non-Majors storeroom, shelf AA3
	Photogates	1	non-Majors storeroom, BB3

Computers Needed?

• Yes.

• Lab Setup (offset tracks as shown below! - see this page for photo details):

  

  ---

• Maximum suspended mass is 50g.

• Use small masses with built-in hooks:

  

  ---

• Track setup:

  Setup for measuring k:

  Note: Set the end stops (where springs attach) on the 100cm and 200cm marks

  

  ---

  Setup for measuring T:

  
  Note: Leave pulley attached to track (omitted for clarity)
