Introduction / Purpose
Circular motion is the motion that links velocity, mass, and radius of the string of an object. If any one of the factors is changed, the motion of the object gets affected or the velocity/acceleration gets affected. All objects going through circular motion experience a force called the centripetal force.
Centripetal force is the force that acts from the center of the circular path and makes the object move in the curve instead of flying out. In other words, centripetal force is the force that originates from the center and is directed inwards. Also, one important factor in this lab is that the circular motion will be horizontal.
In this experiment, the factor that will be changed is the radius of the string. This will bring in a direct change in the motion of the rubber stopper attached to the string. The string will pass through a plastic tube, which
