|MECHANICS - MOTION IN TWO DIMENSIONS - CENTRAL FORCES||Order|
Description: This demonstration shows the magnitude of centripetal force is not necessarily dependant on the spinning mass but also on other factors like angular velocity and radius of travel.
Instructions: A small mass and a large mass are connected together by a string that passes through a cylinder. When you hold the cylinder, the large mass falls pulling the smaller mass to the cylinder. If the small mass is then spun in a circle at a high enough angular velocity, the tension in the string will be enough to hold up the larger mass. Different angular velocities will lift of lower the heavy mass.
Hazards: Be careful that a student (or demonstrator) is not in the path of the smaller moving object.
