Finding the density of solid bodies by measuring the buoyan-cy

Principle

In this experiment the students should recognize that the density of solid objects can be determined by measuring only the buoyancy. The required computations can be given or worked out by the students on their own, in part as an additional Task. The ...

Finding the density of liquids using a hydrometer

Principle

The students should use the knowledge gained from the experiments "Buoyancy" and "Archimedes' principle" to be able to construct a hydrometer.

The correlation between density and immersion depth is to be determined in a preliminary expe ...

Finding the density of immiscible liquids

Principle

Using the knowledge gained in the experiments "Buoyancy and floating" and "Finding the density of solid bodies by measuring the buoyancy", the students should determine the density of petroleum ether in a water-filled U-tube.

After rear ...

Capillary action

Principle

The students should measure the height that water rises in four capillary tubes and investigate the resulting graph.

In a supplementary problem the graph generated by plotting the measured values against the reciprocals of the diam ...

Boyle-Mariotte law

Principle

Using a U-tube made of a piece of tubing and glass tubes, the students should show that the product of pressure and volume of a confined quantity of gas is constant. 

Moreover, they should measure the difference in h ...

Pumps and siphons

Principle

In Experiment 1, the students should make a pressure and suction pump; in Experiment 2, a siphon. The mode of functioning of both should be investigated.

Task

How do pumps and siphons function?

I ...

Helical spring pendulum

Principle

The students have determined the spring constant of springs in Experiment ME 2.4 (Hooke's Law) and had their first experience with an oscillating system in Experiment ME 1.2. In this experiment with a spring pendulum they should discover the factors o ...

Helical spring pendulum

Principle

In this experiment observations are to be made on a spring pendulum which consists of a helical spring
with a spring constant D and a mass m which is hung on it. When the pendulum is displaced by smax and
let go of, it swings across its r ...

Thread pendulum (mathematical pendulum)

Principle

The students have investigated the influence of spring constant and mass on the oscillation period and while doing so have learned the methods required for the investigation of oscillating systems. They should now apply this knowledge usefully to a&nb ...

Oscillations of a leaf spring

Principle

In the previous experiments, the students determined the oscillation period of a spring and of a thread pendulum, and its dependence on the mass. They also determined the spring constant and pendulum length respectively.

In this ex ...

Damping

Principle

In the previous experiments the students have experimented several times with oscillating systems. In contrast, in this experiment they should observe the oscillation amplitudes over longer periods of time, become familiar with their decrease over ti ...

Forced oscillation and resonance

Principle

In the Experiment "Helical spring pendulum" the students have determined the natural frequency of a spring pendulum and established this frequency dependence on pendulum mass and spring constant. In this experiment they should force a spring pendulum ...

Displacement-time recording

Principle

Using the leaf spring which the students have become familiar with in one of the previous experiments, they should now be made familiar with the recording of oscillations in a path-time diagram and attempt its evaluation.

The values det ...

Reversible pendulum (physical pendulum)

Principle

In the "Simple pendulum" experiment (Mechanics 5.2) the students became acquainted with the correlations between pendulum length and oscillation period of a thread pendulum. In the present experiment they should discover the special property of a ...

Coupled pendulum systems

Principle

Using two coupled pendulums, the students should investigate how they interact and determine their beat frequency f_s. Additionally, they should measure the oscillation frequencies for excitation in the same (f₁ ...
