Damped Oscillations - Lab Report Example

Damping occurs when the amplitude of the oscillations The amplitude of these oscillations is time dependent and is inversely proportional to the time.... Higher damping means that the oscillations reduce in their size (Fang et al.... Simple harmonic motion is the behavior of systems that is distinguished by a point of equilibrium, and a force that restores and is proportional to the displacement from that equilibrium....

The number of oscillations per unit time is equal to the frequency.... This shows that as the length of the pendulum increases, the period of the oscillations increases too.... This practical reported that the length and the gravity pull on the pendulum were two factors that affect the oscillations of a pendulum (Dunwoody 10)....

According to Nurst (1999) the term feedback refers to process through which information on future or present events tend to affect similar events in future while a feedback amplifier is that which the fraction of output energy get fed back to an input of that same circuit.... As… These are negative also referred to as inverse or degenerative feedback and the positive also referred to as direct or regenerative feedback....

Using a stopwatch the average time for 10 oscillations was… The process was repeated to generate adequate data that was used to calculate gravitational acceleration and compared with the documented value (9.... In this report, relationship between two broad parameters of a simple harmonic oscillator (pendulum) was investigated....

In this experiment, a mass is set to swing to determine the number of oscillations in a particular period.... Such an experiment is successfully conducted using a bob, timer, thread, and split cork.... With all this apparatus in place, the pendulum is set to… From the data obtained, uncertainty estimates are computed and used to draw a graph....

Free response in this context consists of oscillations at a particular frequency which is natural.... When there is dumping, the 1 Degree of Freedom undergoes decaying oscillations.... If only a single variable is used to describe the position then it is considered a degree of freedom....

In theory, an un-damped freely vibrating system continues to vibrate after it has started.... Un-damped and damped vibration: In un-damped vibrations, no energy is lost or dissipated as a result of friction during the oscillatory motion....

The pendulum was given a twist of 180o and a period of 10 oscillations were measured using a stopwatch and the period for 10 oscillations was found to be 53.... This was repeated for a twist of 360o and this time the period for 10 oscillations was found to be 53.... The period of 10 oscillations was measured for the torsional pendulum with different cylindrical masses attached to it.... The period of oscillations was recorded against the mass of the suspended cylindrical weight....
