a bob hung on a light thread, mounted so that it can swing freely under the influence of gravity.
simple pendulum in American English
noun
Physics
a hypothetical apparatus consisting of a point mass suspended from a weightless, frictionless thread whose length is constant, the motion of the body about the string being periodic and, if the angle of deviation from the original equilibrium position is small, representing simple harmonic motion (distinguished from physical pendulum)
