Angular speed and Angle

Purpose:
The purpose of the lab is to develop a relationship between angular speed and the angle that is created when an object on a string is on attached to an extended arm that is spinning at the constant angular speed.

Equipment Used:

The image is the of the object that has a motor that will spin the top arm at a constant velocity. The string will then create an angle at the constant velocity.

Data Collected:
The arm would spin and using a stopwatch, the time to take nine revolutions was measured. After the time was measured, the height that the object was above the ground was measured. This was done for eight different angular speeds.

Calculations:

The angle can be calculated because the length of the string is constant and the variable that is changing is the height the object is above the ground. Using only the two the lengths, the angle could be calculated. Once the angle is calculated, the value of the angular speed can be calculated. This value can be compared to the measured angular speed.

Conclusion:
The measured angular speed was very close to the calculated value. The percent error was -4.77% and that is considerably small.
