Physics Investigation: Does the Mass Effect the Acceleration of Each Person While Going Down the Slide?
Physics Investigation
Investigation Question:
Does the mass effect the acceleration of each person while going down the slide?
Hypothesis: The heavie
How will we take measurements?
Using the equations:
V= u+at s=ut + .5 at2
Measure the overall distance the mass will be travelling. To calculate the time it took to reach the end of the ramp, then using the equations above, add in the distance, time, and initial velocity.
Variables
Independent:
Difference of weight on each car.
Dependent:
Time and velocity of the car going down the ramp
Controlled:
Size of the ramp
Same car used
Same size weights
1x power pack (set to A/C)
Equipment:
1x wooden ramp
1x model car
5x 1kg weights
1x stopwatch
1x role of ticker timer tap
1x ticker timer
Method:
1. Gather all equipment listed above
2. Set up ramp, car (without any weights) and ticker timer (repeat 2 time)
3. Push car down the ramp and record time
4. Repeat experiment by adding on 1 1kg weight each time
5. Record all results into a table
6. Put all equipment away once finished
Results:

Evaluation:
What we have found is that the velocity of each car carrying different amounts of weight is roughly the same. This is because the ticker timer error of 15% and also because gravity pulls each object at the same rate and with no push or pull forces acting on the car, they all accelerated at the same rate. The person who timed the car as it rolled; there could have been a delay because of that person’s reaction time.
Conclusion:
Our group found that each car went down the ramp at roughly the same time. Our hypothesis did not match what we
