Lab 9: Single Harmonic Motion Flashcards
1
Q
What law was studied in this experiment of Single Harmonic Motion?
A
Hookes Law. F=-kx
2
Q
How much mass was added to the spring as M=0?
A
250grams including the 50g weight hanger was added to the spring. This was considered to be the M=0 mark for the rest of the experiment.
3
Q
When M=350, how much weight is actually on the spring?
A
M=600, because the starting point M=0 was actually 250 grams.
4
Q
T/F: the period of oscillation is how long it takes the spring to go from the top to the bottom.
A
False: spring moves from the top to the bottom to the top, its starting point.
5
Q
Sources of error:
A
- inaccurate measurement of mass of spring,
- inaccurate measurement of recording of hte position of —-the bottom of the weight hanger
- sideways motion affecting period of oscillation
- inaccurate timing of period.
- kinetic energy transfer to wood
