Oscillations - Mechanics

Mechanics : Oscillations

Detect and record earthquakes using a Seismometer, investigate free, forced, and chaotic oscillations with the Torsion Pendulum, use the Variable Gravity Pendulum to determine the period of oscillation as a function of the pendulum length and of the acceleration due to gravity. Experiment with the Rotation Apparatus to determine the angular acceleration as a function of torque and the moment of inertia as a function of the distance of the body from the axis and its mass. «««

Chaos Pendulum

Defined as an extreme sensitivity to initial conditions, chaos theory is an important field of study in modern physics. The addition of a second leg transforms the predictable pendulum into an outstanding demonstration of chaotic motion. The Chaotic Pendulum is made of Aluminium with brush-finished anodised coating. These pendulums ...
