Objective:
The purpose of this experiment is to understand the concepts of uniform circular
motion. A uniform circular motion is defined as motion at a constant speed on a circular
path. Through out this lab we will measure the acceleration directed toward the center of
the circle, also know as centripetal acceleration, in relation to the speed of the weighted
object spinning and the radius of the circle.
Theory:
In order to calculate the centripetal acceleration that will be denoted as
a
c
, we will use
the equation
a
c
= (v
2
)/r
Here
v
will be the velocity of the spinning mass and
r
is the radius of the circle.
However, we do not know the velocity of the object yet, to complete the calculation for
the velocity of the object we used the equation
v= (2πr)/T
That requires only the radius and the period for one revolution,
T
.
After simple algebra,
velocity can also be expressed as:
v=2πrf
Where
f
is the frequency, the number of revolutions per unit time (1/
