LABORATORY #B
Simple Harmonic Motion
1.
OBJECTIVE
-
To determine the spring constant
k
by stretching the spring and applying
Hooke’s Law.
-
To verify that the period of vibration of a body on a spring is independent
of the amplitude, and is given by:
=
T
2πmk
-
To measure the period T of a simple pendulum as a function of the length
L of the pendulum and to verify that it is given by:
=
T
2πLg
