OSCILLATIONS

Objective: Measuring the period of oscillation of a string pendulum with bobs of various masses. The period of oscillation T for a string pendulum is dependent on the length of the pendulum L, but does not depend on the mass of the bob m ... more

Objective: Description of elliptical oscillations of a string pendulum as the superimposition of two components perpendicular to one another Depending on the initial conditions, a suitable suspended string pendulum will oscillate in such ... more

Objective: Measure the period of an oscillating pendulum as a function of the effective component of the gravitational acceleration The period of a pendulum is lengthened by tilting its axis away from the horizontal, since the effective ... more

Objective: Work out the local acceleration due to gravity with the help of a reversible pendulum A reversible pendulum is a special design of a normal physical pendulum. It is able to swing from either of two mounting points and can be set ... more

Objective: Demonstrate the rotation of the earth with a Foucault pendulumA Foucault pendulum is a long string pendulum with a heavy bob, which can be used to demonstrate the rotation of the earth. In this experiment, a pendulum 1.2 metres ... more

Measure the oscillations of a coil spring pendulum using an ultrasonic motion sensor The oscillations of a coil spring pendulum are a classic example of simple harmonic oscillation. In this experiment, those oscillations are recorded by ... more

Objective: Measurement and analysis of simple harmonic rotary oscillation Pohl’s wheel or rotating (torsional) pendulum allows for the investigation of simple harmonic rotary oscillation. The only forces acting on the wheel are the restoring ... more

Objective: Measurement and analysis of forced harmonic rotary oscillation Pohl’s wheel or rotating (torsional) pendulum allows for the investigation of forced harmonic rotary oscillation. For this purpose, the oscillating system is connected ... more

Objective: Record and evaluate oscillation of two identical coupled pendulums The oscillation of two identical, coupled pendulums is distinguished by the period of oscillation and the beat period. The beat period is the interval between ... more

Objective: Investigate standing waves along a stretched coil spring and a taut ropeSome examples of where mechanical waves arise include a stretched coil spring, where the waves are longitudinal, or a taut rope where the waves are transverse ... more
