Question

Physics

  1. Use the kinematic equation, df = ½ at2,to calculate the acceleration of each object in Table 1. Record thecalculated acceleration in Table 1.

2.    Show a sample calculation:

Table 1: Average Free Fall Time for VariousObjects

Drop
Height (m)

Object

Average Free Fall
Time (s)

Calculated
Acceleration (m/s2)

0.865 ± 0.001

Coffee filter

0.625

Cork

0.435

Marble

0.424

Wooden Block

0.421

3. Answer all of the Post-Lab Questions (Note: Information tohelp with these questions may be available in the Gravity LabIntroduction)

  1. How does the rate of acceleration you calculated for eachobject compare? Are they similar or different? Why?
  1. The acceleration due to gravity calculated this way works wellfor objects near the Earth’s surface. How would you have to changethe equation if the object was 100,000 meters above theground?
  1. How does air resistance alter the way we perceive fallingobjects?
  1. Is the force acting on a massive object larger than that actingon a less massive one? How can you verify this without taking anymeasurements?
