What causes simple harmonic motion?

The simplest oscillations occur when the restoring force is directly proportional to displacement. Recall that Hooke’s law describes this situation with the equation F = −kx. Therefore, Hooke’s law describes and applies to the simplest case of oscillation, known as simple harmonic motion.

What force causes the SHM in the pendulum system?

The restoring force causes the vibrating object to slow down as it moves away from the equilibrium position and to speed up as it approaches the equilibrium position. It is this restoring force that is responsible for the vibration.

What is force in SHM?

The force responsible for the motion is always directed toward the equilibrium position and is directly proportional to the distance from it. That is, F = −kx, where F is the force, x is the displacement, and k is a constant. This relation is called Hooke’s law.

What is meant by forced oscillation?

Forced oscillations occur when an oscillating system is driven by a periodic force that is external to the oscillating system. In such a case, the oscillator is compelled to move at the frequency νD = ωD/2π of the driving force.

What causes oscillation of a system?

If a constant force such as gravity is added to the system, the point of equilibrium is shifted. In the spring-mass system, oscillations occur because, at the static equilibrium displacement, the mass has kinetic energy which is converted into potential energy stored in the spring at the extremes of its path.

Where will be the force acting on a particle executing SHM maximum?

It is maximum at the extreme positions where the displacement is maximum and minimum at the mean position (displacement = 0).

How do you find force constant in SHM?

In this case the force can be calculated as F=-kx, where F is the restoring force, k is the force constant, and x is the displacement. The motion of a mass on a spring can be described as Simple Harmonic Motion (SHM): oscillatory motion that follows Hooke’s Law.

What are forced oscillations HSC?

When a body oscillates by being influenced by an external periodic force, it is called forced oscillation. Here, the amplitude of oscillation, experiences damping but remains constant due to the external energy supplied to the system.
