MOTION: Simple harmonic motion (SHM)
A mass is attached to a spring of spring constant 60 N/m along a horizontal, frictionless surface. The spring is initially stretched by a force of 5.0 N on the mass and let go. It takes the mass 0.50 s to go back to its equilibrium position when it is oscillating. What is the amplitude?
Increasing the amplitude of a mass-and-spring system causes what kind of change in the resonant frequency of the system? (Assume no other changes in the system.)
For a forced vibration, the amplitude of vibration is found to depend on the:
A mass on a spring undergoes SHM. When the mass passes through the equilibrium position, its instantaneous velocity:
What happens to a simple pendulum's frequency if both its length and mass are increased?
