Lab Report # 4
Lab Report Title: Elasticity and Oscillations
Name: Mary Jan D. Dizon
Section: BSCE-1E
Schedule: S 5:00-8:00PM
Objective:
- to identify the Hooke’s law
- To identify the force that applied on the garter
• Method:
- Hooke's law is given by F=k*x, where "F" is the applied force,
"k" is the spring constant, and "x" is the material's extension,
which is final length minus initial length. The unit of force is
"N" for "newton," the unit of k is "N/m," but in this
experiment, the unit is "N/cm," and the unit of extension is
"cm."
In this experiment, force is known by F=mg, where "m"
represent mass and "g" is gravity's acceleration. And
gravity's acceleration can be 9.80 m/s ^2.The value of
acceleration of gravity used in this experiment was 9.80
m/s^2.?
Formula
F = k * x k = F/x?
