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.

Q

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

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
