In physics and mathematics, in the area of dynamical systems, an elastic pendulum[1][2] (also called spring pendulum[3][4] or swinging spring) is a physical system where a piece of mass is connected to a spring so that the resulting motion contains elements of both a simple pendulum and a one-dimensional spring-mass system. [2]
Spring Pendulum. equ. Instructions: In a simple pendulum, we consider a particle attached to a rigid, lightweight rod. For a spring pendulum, on the other hand, we replace the rod with a spring (which we assume doesn’t bend as the particle moves).
Example (Spring pendulum): Consider a pendulum made of a spring with a mass m on the end (see Fig. 6.1). The spring is arranged to lie in a straight line (which we can arrange q l+x m Figure 6.1 by, say, wrapping the spring around a rigid massless …

2024年5月20日 · We introduce a one-dimensional coordinate system to describe the position of the mass, such that the \(x\) axis is co-linear with the motion, the origin is located where the spring is at rest, and the positive direction corresponds to the spring being extended. This “spring-mass system” is illustrated in Figure \(\PageIndex{1}\).
2017年7月19日 · The spring is assumed to have a force constant $k$ and an equilibrium length $l_0$ such that its potential energy when extended or compressed to a length $l$ is $\frac{1}{2}k(l-l_0)^2$. The components of the bob's position and velocity are:
A torsional pendulum consists of a rigid body suspended by a light wire or spring (Figure 15.22). When the body is twisted some small maximum angle ( Θ ) ( Θ ) and released from rest, the body oscillates between ( θ = + Θ ) ( θ = + Θ ) and ( θ = − Θ ) ( θ = − Θ ) .
