Damping is not to be confused with friction, which is a type of dissipative force acting on a system. Friction can cause or be a factor of damping. The damping ratio is a dimensionless measure describing how oscillations in a system decay after a disturbance.
Damping is a frictional force, so it generates heat and dissipates energy. When the damping constant b is small we would expect the system to still oscillate, but with decreasing amplitude as its energy is converted to heat.
4 Απρ 2023 · Damping is defined as: The reduction in energy and amplitude of oscillations due to resistive forces on the oscillating system. Damping continues until the oscillator comes to rest at the equilibrium position; A key feature of simple harmonic motion is that the frequency of damped oscillations does not change as the amplitude decreases
Describe the difference between overdamping, underdamping, and critical damping. Answer. An overdamped system moves slowly toward equilibrium. An underdamped system moves quickly to equilibrium, but will oscillate about the equilibrium point as it does so.
Friction of some sort usually acts to dampen the motion so it dies away, or needs more force to continue. In this section, we examine some examples of damped harmonic motion and see how to modify the equations of motion to describe this more general case.
Explain the difference between overdamping, underdamping, and critical damping, providing a real-world example for each.
In these notes, we complicate our previous discussion of the simple harmonic oscillator by considering the case in which energy is not conserved. Specifically we consider how the dynamics and kinematics of the oscillator change when we subject it to a velocity-dependent damping force.
