Centripetal Acceleration v Angular Frequency
Isaiah Hernandez and Tony Wu
Purpose: To determine the relationship between centripetal acceleration and angular speed.
Theory/intro: Centripetal acceleration is the inward acceleration of object. It is denoted by the formula ar = v2 / r.
A summary of apparatus/experimental procedure:
Collect period and acceleration data for a variety of rotational speeds by varying the voltage from the power supply feeding the scooter motor.
A list/table of your measured data:
Data table of varying mass, radius, or omega.
A list/table of your calculated result(s)/Graphs of your data:
This graph showsthe effect of varying the radius of the apparatus.
This graph shows the effect of varying the omega of the apparatus.
This graph shows how the effect of varying the mass of the apparatus.
This graph shows the effect of varying the omega of the apparatus.
This graph shows how the effect of varying the mass of the apparatus.
Conclusions:
An increase or decrease in one out of the three variables that make up centripetal acceleration (mass, radius, or omega) led to a proportional increase in the other two variables as analyzed from the formula for centripetal force:
