The damping of free mechanical harmonic oscillations is associated with a decrease in mechanical energy due to the action of resistance and friction forces.]]> 2022-01-20 05:28:54 UTC https://padlet.com/mike1teac/keztr68h1q94evrt/wish/2002069518 Damped Oscillation and Energy change https://padlet.com/mike1teac/keztr68h1q94evrt/wish/2002069743 2022-01-20 05:29:07 UTC https://padlet.com/mike1teac/keztr68h1q94evrt/wish/2002069743 B) https://padlet.com/mike1teac/keztr68h1q94evrt/wish/2002071569 The energy transported by a wave is directly proportional to the square of the amplitude]]> 2022-01-20 05:30:41 UTC https://padlet.com/mike1teac/keztr68h1q94evrt/wish/2002071569 Critical damping reduces the amplitude of the oscillations to zero in the shortest possible time, returning the system to the equilibrium point.

Any completely isolated system exhibiting simple harmonic motion will carry on swinging/vibrating forever! It conserves mechanical energy. There will be continuous interchange of kinetic to potential energy and back again. 
For example,  
In a spring-mass system, the energy conversion is between kinetic energy and the potential energy stored in a stretched or compressed spring. 
In a pendulum, the energy is converted between kinetic energy and gravitational potential energy.
