1. Experiment 1 : Angular Velocity
(1). Introduction
In linear dynamics, Newton's second law() describes the relationship between force, mass, and acceleration for an idealized point particle. No real object is a point particle, but this idealized relationship can be extended to real objects by defining a point called the center of mass of the object. Using this concept, a more generalized version of Newton's second law still holds. F is taken as the vector sum of all the external forces acting on the object, m is the mass of the object, and a is the acceleration of the center of mass.
However, an object can move while its center of mass remains stationary. in this experiment, we studied the simplest and most important motion of this type: rotation about a fixed axis through the center of mass of the object. This is an important kind of motion because any motion of a rigid body can be described as a combination of the motion of its center of mass, and rotation about its center of mass.
