Because of this, the spring-mass system is called a linear simple harmonic oscillator. Substituting the expressions for acceleration and displacement in Newton's second law, the equation for angular frequency can be obtained. The angular frequency depends only on the force constant and the mass, ...
How can the motion of a mass-spring system be described mathematically? The motion of a mass-spring system can be described using the equation x = A cos(ωt + φ), where x is the displacement, A is the amplitude, ω is the angular frequency, and φ is the phase constant. This equa...
