Phy - Lab Relationship Between Angle and Acc

Extracts from this document...

Introduction

Lab Report - Relationship between Angle and Acceleration Aim To get the gravitational acceleration by a slope board and a ticker tape. Hypothesis When the angle of the board gets 90, then the acceleration reaches at 9.81m/s2 which is the speed of the gravitational acceleration. Apparatus A slope board, ticker tape, a car, and a tractor. Method 1. Put the board on a table or something to put over. 2. Measure the angle(starts from 1 degree, 11 degree, 22 degree, 33 degree, and 44 degree) 3. For each angle, place the ticker tape on the top of the board, and let the car go from a ticker tape as long as possible. ...read more.

7. From the Time-Velocity graphs, get a gradient (Acceleration) of each graph and make a final table for an Angle-Acceleration graph. 8. At the final graph, the acceleration at 90 degree will be presented.

Conclusion

My final graph is not closer to the original gravitational acceleration. I may say my hypothesis is not wrong, because it's from the error such as timing error, uncertainties error in timing or angle. I think the most affected reason is that the friction on the board when the car moves. And also I was trying to do the experiment for every 11 degrees if I could. However, it was nearly impossible to do when the angle gets over 50. If I were able to measure every 11 degrees then my final result would be closer to the value that should it be (9.81m/s2) ?? ?? ?? ?? HanSol Shin 11A IB Physics SL - 1 - ...read more.

The point where the brick made contact with the ground was marked and so it was easier to measure the length.
