Uniformly Accelerated Motion: Inclined Plane
Purpose: How does mass effect acceleration
Procedure:
1. Place marble on the inclined track at the distance specified on your data sheet.
2. When the marble is released, start your electronic timer. When the marble strikes the stopping
block, record the elapsed time in units of seconds.
3. Repeat your measurements for this distance two more times, recording the elapsed time in your
data table.
4. Repeat the experiment for other distances in your data table.
5. Repeat the entire experiment for the lighter mass.
6. Plot graphs of distance vs. average time for each marble.
7. Make graphs of distance vs. average time squared for each marble.
8. Use your graphs to answer the questions given in the laboratory.

If you increase the inclination of the grooved track, will the marbles roll faster or slower? Why?
List the possible errors you cannot avoid in performing the experiment.
Why should you note the “elapsed time” three times?
Does the experimental result refute Aristotelian Physics of Motion?
If a ball falls 10 meters in 2 seconds, what is the acceleration?
What does the shape of the distance vs. (time)2 graph indicate?
