Rotterdam designer David Derksen has decorated a set of plates by employing the oscillations of a pendulum to drip patterns of paint (+ movie). The patterns on Derksen's prototype Oscillation Plates ...

A physical pendulum undergoes simple harmonic motion when displaced by a small angle. The oscillations are no longer simple harmonic motion when it is released from a large angle. The pendulum's pivot ...

When oscillating, the pendulum slowly shifts between torsional and vertical modes of oscillation. When stretched down, the spring applies a torque to the mass to help it unstretch. When compressed up, ...

A basic pendulum is a mass at the end of a string that swings back and forth. It seems simple, and it appears in most introductory physics textbooks. But it's not a trivial problem to solve for the ...

A Foucault pendulum, or Foucault's pendulum, named after the French physicist Leon Foucault, was conceived as an experiment to demonstrate the rotation of the Earth; its action is a result of the ...

In 1851, the French physicist Léon Foucault provided an experimental proof of the Earth’s rotation using a pendulum. Although Foucault is best known for this ingenious experiment, he also made several ...

THE oscillations of a long pendulum are observed to describe an ellipse the axis of which tends to set itself at right-angles to the plane in which the pendulum was started. An explanation of the ...
