Centripetal and Centrifugal

In the second part of the lab, we spun around the string at different radius's but with the same speed. It turned out that when the radius is smaller, then the faster the object will move. The reason for this is because the smaller the radius, the less amount of distance or circumference the object will have to travel.
Before we performed the lab, I hypothesized that the object will go forward when the string is released because inertia takes over. For the second part I hypothesized that the smaller the radius, the faster it will go. I hypothesized this because the smaller the radius, the less distance the object will have to travel. This enables the object to move much faster when it is closer to the center. These hypotheses were correct.
As a final conclusion I can say that if an object is spun around and then released, then the object will fly off forward and if the radius of the object is shortened then the object will move faster, for it has less distance to cover.
