# Rubber Band Lab

Extracts from this document...

Introduction

Lab Report - Relationship between Angle of Release and Distance Traveled Aim The aim is to establish the maximum distance traveled by a rubber band under a constant release strength. To shoot a rubber band as far as possible. How does the angle of release affect the distance traveled? Hypothesis When the angle of release is increased, the distance will increase up to 45 degrees which is the optimum, and it will decrease after 45 degrees. Constants/Variables Constants - Height of Release (60cm from the ground) ...read more.

Repeat it three times for each angle. 5. For each angle, if the data is considerably higher or lower than the other measurements, ignore it and do it once more to obtain more accurate data.

Conclusion

During the experiment, certain measurements were really off the mark. For example, when measuring for the angle of 15 degrees, a result of 6 meters was recorded while the probable range was near 4 meters. There is no clear explanation for that but it seems that the release strength may not have always been constant. It is also possible that during the experiment some settings like height and angle of release may have been inadvertently modified by the operator. It would therefore be advisable to do more than 3 trials for each release angle in order to obtain more accurate data. ?? ?? ?? ?? IB Physics SL ...read more.
