Hooke's+Law

Hooke's Law =**Needs Adjusting.**=
 * F-kx and the equation for simple Harmonic motion need to be fixed. F=kx is a static situation.**

By: Tony Spalding and Brian Florin Verify Hooke's Law (F=kx) by finding the spring constant (k) and comparing results from this equation to the spring constant found using the equation T=2π * √(m/k). Use the percent difference formula to compare results for k.
 * Objective:**

1. Adjust the program as follows: a) Adjust the friction setting to "none". b) Leave all other settings untouched. The "stopwatch" will be of use later. c) Drag the ruler so that the 0 is at the horizontal dotted line. It may be moved horizontallyunder any of the springs.2. Load the a mass onto spring one.3. Observe the amplitude (x) and calculate force.4. Plug values into the equation to find spring constant (k).5. Repeat using three masses total, all of different values.6. Enable the "stopwatch" option.7. Oscillate the mass on spring number one and use the stopwatch to find the period (T).8. Find k using the equation T=2π * √(m/k). 9. Repeat steps 7 and 8 using three total masses, all different. 10. Plot points on a graph so that slope equals k value.
 * Data Collection Techniques:**

1. Calculate k value using two equations and calculate percent difference. 2. Do different masses effect the period of oscillation? Why or why not? 3. Which do you believe is the better method for finding the k value? Why or why not?
 * Analysis Questions:**

Graph force vs. displacement, where the slope will represent the average k-value. Percent difference between the calculated k-value using Hooke's Law and period equation of the same mass.
