Centripetal force with motor

Purpose:  We must come up with a relation between theta and omega from an apparatus that swings a mass at the end of a string in a horizontal circle.

Process: 

1) To obtain the angle theta we can look at the right triangle that is formed by the string and the angle it makes with the origin. Using trigonometry we can obtain the angle.

2) To obtain omega we can time how long it takes for the stopper to make revolutions, or one complete circle, around the shaft device.

3) We can get the height from the floor to the mass by increasing the voltage to measure different heights which will give us different omegas also correspondingly.

4) We then record data of the omega and acceleration relations using logger pro. 

Conclusion: We can find the relation between the angle and omega by trigonometry and calculating other components such as velocity and tension. Different heights can be calculated and which will change the the angle and omega, experimenting with different trials and data to get different scenarios for different values.
