# The Relationship between Acceleration and Rolling Angle

Extracts from this document...

Introduction

The Relationship between Acceleration and Rolling Angle

## Design

The purpose of this experiment was to assess whether or not there is a directly proportional relationship with respect to the acceleration (a) of a ball descending from the height of a ramp, and the ramp’s angle (θ). It can then be inferred that an increase in the angle (θ) of the ramp, would render an increase in the acceleration (a) of the ball. If the acceleration (a) is to increase, then by Newton’s Second Law of Motion (the Law of Inertia), the increase in acceleration (a) must be a direct result of an increase in force, considering the mass doesn’t change.

Newton’s Second Law of Motion states that:

Force = (; where force = ΣFn = net force, mass is measured in kilograms, and acceleration is measured in ms-1

acceleration=

Conclusion

-2. Another improvement could have been to have an automatic timer to eliminate human error with respect to the time trials. The timing of the ball rolling down the ramp is subjective to some degree, though it is timed with a timer, it is subjective to some degree, as the student doing the timing decides when to stop and start. A longer ramp may have improved the time trials, as the time interval to measure steeper angles would not have been so small.  A smoother ball such as a bowling ball (on a much larger apparatus), or a billiard ball would have been more effective as some of the frictional force would have been reduced. Lastly, the inclusion of measurements of uncertainty would have helped as it would have been easier to assume whether or not the inaccurate results were acceptable.

All measurements were rounded to second decimal place. The next step to measure the acceleration was constructing the graph showing the distance dependence on time (Graph 1). The best-fit line was drawn, so were the line of maximal slope and the line of minimal slope. Then, the Graph 2 showing the average acceleration dependence on time was constructed.

Error also came from inability to know exactly when to stop the timer; also the additional seconds-reaction time of the experimentator. Given errors could cause further errors in calculations of accelerations. All errors have reasonable values. The values of the measurements are similar to each other.
