What is differential equation of motion for damped oscillation?
What is differential equation of motion for damped oscillation?
(ii) resistive force of medium which is proportional to velocity and opposite to the direction of velocity, i.e. F2 = –bv The net force acting on the load is, F = Fx1 + F2 = – ky –bv. Therefore the equation of motion of load is, This is the required differntial equation of motion of damped oscillations.
What is the equation of displacement in SHM?

What is the damped harmonic oscillator write its equation of motion?
Therefore, the total force acting on the mass at any time t is, F = -kx -bυ. This expression shows that the damping decreases exponentially with time. Obviously, if we put b = 0, all equations of damped simple harmonic motion will turn into the corresponding equations of undamped motion.
What is damped oscillator?
A damped oscillation means an oscillation that fades away with time. Examples include a swinging pendulum, a weight on a spring, and also a resistor – inductor – capacitor (RLC) circuit. We can use these equations to discover when the energy fades out smoothly (over-damped) or rings (under-damped).
What is damped harmonic oscillator?
Damped harmonic oscillators are vibrating systems for which the amplitude of vibration decreases over time. These are second-order ordinary differential equations which include a term proportional to the first derivative of the amplitude.
How do you find the total displacement?
The average velocity of the object is multiplied by the time traveled to find the displacement. The equation x = ½( v + u)t can be manipulated, as shown below, to find any one of the four values if the other three are known.
