5. Hypothesis
Our hypothesis:
Gravity is a form of downward acceleration that
is caused by the mass of the earth acting on
objects and is calculable using various
methods.
TL;DR:
Gravity is acceleration and can be
calculated
9. Procedure and Process:
Let’s be creative
Experiment A: Using the Pasco Sensors with Sparkvue
Experiment B: Dropping an object from a height and
recording the process with a high frame rate camera
Experiment C: Releasing a physics car on a slope
attached to ticker tape.
30. General Errors
Limitation: Used a rectangular wooden block for
measurements.
● May have caused more air resistance due to larger
surface area.
Improvement:
● Use a denser, brightly coloured cube for easier
identification.
● However, this may be harder for the Pasco Sensors to
track due to a decreased surface area.
31. Human Error: Held the sensor against the wall.
● We may have accidentally shifted it, altering what the
sensor would pick up.
Improvement:
● Use tape to lock the sensor in position after making
sure it is level.
Experiment A
32. Human error: We were not certain as to when the drop
actually started.
● It was difficult to judge in which frame in the video was
the block actually released.
● Our perception may have affected the results.
Improvement:
● Use better lighting
● Mark a definitive line to determine the beginning of the
drop.
Experiment B
33. Limitations:
● Friction between physics car and slope.
● Resistance from the pull of the ticker tape.
These forces slow down the movement of the block,
skewing the results.
Improvement:
● There are no effective ways of eliminating the friction
between the board and the physics car.
Experiment C
