    "Force" derivation of Figure 1. Force diagram of a simple gravity pendulum. Consider Figure 1 on the right, which shows the forces acting on a simple pendulum. Note that the path of the pendulum sweeps out an arc of a circle. The angle θ is measured in radians, and this is crucial for this formula.

  3. Cavendish experiment - Wikipedia

    en.wikipedia.org/wiki/Cavendish_experiment

    Cavendish's diagram of his torsion pendulum, seen from above. The pendulum consists of two small spherical lead weights (h, h) hanging from a 6-foot horizontal wooden beam supported in the center by a fine torsion wire.

  4. Foucault pendulum vector diagrams - Wikipedia

    en.wikipedia.org/wiki/Foucault_pendulum_vector...

    The pendulum bob is always affected by the force of gravity directed towards the center of the Earth. The force associated with the connection of the pendulum to a support structure directs the pendulum bob along the swing of the arc. The support structure is dependent on the velocity of the surface of the Earth where it is located.

  5. Pendulum - Wikipedia

    en.wikipedia.org/wiki/Pendulum

    "Simple gravity pendulum" model assumes no friction or air resistance. A pendulum is a device made of a weight suspended from a pivot so that it can swing freely. [1] When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position.

  6. Elastic pendulum - Wikipedia

    en.wikipedia.org/wiki/Elastic_pendulum

    2 DOF elastic pendulum with polar coordinate plots. [6] The system is much more complex than a simple pendulum, as the properties of the spring add an extra dimension of freedom to the system. For example, when the spring compresses, the shorter radius causes the spring to move faster due to the conservation of angular momentum. It is also ...

  7. Complex harmonic motion - Wikipedia

    en.wikipedia.org/wiki/Complex_harmonic_motion

    In physics, complex harmonic motion is a complicated realm based on the simple harmonic motion.The word "complex" refers to different situations. Unlike simple harmonic motion, which is regardless of air resistance, friction, etc., complex harmonic motion often has additional forces to dissipate the initial energy and lessen the speed and amplitude of an oscillation until the energy of the ...

  8. Double pendulum - Wikipedia

    en.wikipedia.org/wiki/Double_pendulum

    A double pendulum consists of two pendulums attached end to end.. In physics and mathematics, in the area of dynamical systems, a double pendulum, also known as a chaotic pendulum, is a pendulum with another pendulum attached to its end, forming a simple physical system that exhibits rich dynamic behavior with a strong sensitivity to initial conditions. [1]

  9. Barton's pendulums - Wikipedia

    en.wikipedia.org/wiki/Barton's_pendulums

    A schematic diagram of the Barton's pendulums experiment. First demonstrated by Prof Edwin Henry Barton FRS FRSE (1858–1925), Professor of Physics at University College, Nottingham, who had a particular interest in the movement and behavior of spherical bodies, the Barton's pendulums experiment demonstrates the physical phenomenon of resonance and the response of pendulums to vibration at ...
