Lab 9: Single Harmonic Motion

Question 1

What law was studied in this experiment of Single Harmonic Motion?

Answer 1

Hookes Law. F=-kx

Question 2

How much mass was added to the spring as M=0?

Answer 2

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.

Question 3

When M=350, how much weight is actually on the spring?

Answer 3

M=600, because the starting point M=0 was actually 250 grams.

Question 4

T/F: the period of oscillation is how long it takes the spring to go from the top to the bottom.

Answer 4

False: spring moves from the top to the bottom to the top, its starting point.

Question 5

Sources of error:

Answer 5

• 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
