Hooke’s Law
Name
Abstract;
Include instead of these lines the objectives of the lab (what you investigated), the short description of how you did it and the conclusions formulated based on the obtained results.
It should be ½ to 1 page long.
Picture of the experimental set up
Read the Instructions and Procedure from the HOL lab manual.
Record the cumulative stretch ( elongation) for one spring . Make sure you don’t stretch the spring beyond the elasticity limits.

Calculations and Analysis
1. Plot the Force (y-axis) vs elongation (x-axis) on a computer spreadsheet or on piece of paper. Insert the graph (Excel or picture) in the space below:
2. Find the spring constant for the spring in Newton/meters from the slope the graph. (Refer to the Excel tutorial in the Introduction section or/and read ecampus instructions.
k=
3. A student measured 15s for the 20 complete oscillations for an object of 200g attached at the free end of a spring. Calculate the period of oscillation (T) and the spring constant (k).
Write the equation used and then the numerical values.
