Design

Aspect 1

The aim of this experiment is to prove that acceleration due to gravity is 9.81 m/s.

Hypothesis

We believe that by using a ramp and a marble that we will be able to prove that acceleration due to gravity is 9.81 m/s.

-Explanation

We think this will happen because gravity pulls the marble down to the bottom of the ramp, and if acceleration due to gravity is 9.81 m/s then the data from the trials will show that it is true.

-Predictive Graph

If I were to make a graph for this experiment it would be a velocity and time graph with a straight line that goes in a positive direction; as the time increases the velocity does too.

Conclusion

Aspect 2

The ramp was an overall good apparatus to use for this experiment, although some things were not taken into account that should have been.

  1. Our measurements for the meter stick are not very accurate because we used two different meter sticks. ( we started and stopped)
  2. We had trouble timing when the marble stopped correctly, we originally had 5 trials but only selected three this is random era and cause uncertainties in our data.

Aspect 3

The investigation could have given more accurate results if the following modifications were made in the future:

  1. We could have measured the angle where the two parts of the ramp meet to be more accurate the second time we started the experiment.
  2. Timing issues related to human reaction could have been avoided if we used a type of computer software to track the acceleration of each position.

    The slope is steeper when acceleration is higher because the mass of the Weight was greater so the total mass was greater. If Newton 2nd law is correct and if our measurement is precise, the acceleration that we measured by measuring the time should be similar to the acceleration predicted
