For vibration quantities, a distinction is made between the vibration velocity, the vibration displacement (vibration amplitude), and the vibration acceleration.
What is vibration and how is it created?
An oscillation is a periodic movement around a rest position. It can occur in various fields, such as physics, mechanics or acoustics.
Vibrations occur when a system is deflected from its rest position and then returns to its rest position by a restoring force. This restoring force can be a spring, gravity or the elasticity of a material, for example. As soon as the deflection has occurred, the system begins to oscillate.
There are different types of oscillations, such as harmonic oscillations, where the restoring force is proportional to the deflection, or damping, where the oscillation decreases with time. Vibrations can also be stimulated by external influences such as sound waves or electromagnetic waves.
Oscillations have a certain frequency, which indicates how often the system moves back and forth per unit of time. The amplitude indicates the maximum deflection of the system. Vibrations can be observed in many different areas, such as pendulums, musical instruments or electromagnetic waves.

How can you measure the frequency of an oscillation?
The frequency of an oscillation can be measured in various ways. Here are some common methods:
1. Use an oscilloscope: An oscilloscope is an electronic measuring instrument that is used to display oscillations and signals. It can display the frequency of an oscillation directly.
2. Use a frequency counter: A frequency counter is a specialized measuring device that is used to measure the frequency of a signal. It counts the number of oscillations per unit of time and indicates the frequency in Hertz (Hz).
3. Use a stroboscope: A stroboscope is a device that generates intermittent light. By adjusting the flashing frequency of the stroboscope to the oscillation frequency, you can visually read the frequency of the oscillation.
4. Use a frequency generator: A frequency generator is a device that generates electronic signals. By setting the desired frequency on the frequency generator, you can determine the frequency of an oscillation.
5. Use a sound or audio frequency app: There are also smartphone apps that can measure the frequency of sound or tones. These apps use the smartphone's microphone to record the sound and display the frequency.
It is important to note that the accuracy of the measurement depends on various factors, such as the quality of the measuring instrument and the stability of the vibration. It is therefore advisable to take several measurements and use the average value to obtain more accurate results.

How are vibration and acceleration related?
Vibration and acceleration are closely linked. In an oscillation, an object moves regularly back and forth around a rest position. Acceleration is the change in the speed of an object per unit of time.
In an oscillation, there is always a point at which the object is at rest and its speed is at its highest. At this point, the acceleration is zero, as there is no change in speed. This point is referred to as the reversal point or turning point.
At the outermost points of the oscillation, the so-called amplitudes, the speed of the object is minimal and the acceleration is maximum. A maximum change in speed occurs here, as the object reverses its direction. The acceleration is greatest here and opposite to the direction of movement.
Overall, it can be said that the acceleration in an oscillation is always greatest when the speed is lowest and vice versa. The exact relationship between vibration and acceleration depends on the type of vibration (e.g. harmonic vibration, damped vibration, etc.).

How can you determine the amplitude of an oscillation and what does it mean?
The amplitude of an oscillation can be determined in different ways, depending on the type of oscillation.
In the case of a harmonic oscillation, such as a pendulum motion, the amplitude can be determined directly from the maximum deflection of the pendulum. The distance between the rest position and the point at which the pendulum deflects to its maximum is measured.
In the case of a sound or electromagnetic wave, the amplitude can be defined as the maximum deflection or strength of the wave in relation to its rest position. It can be determined by measuring the maximum pressure change for a sound wave or the maximum field strength for an electromagnetic wave.
The amplitude of an oscillation indicates how strong the oscillation is or how far it is from the rest position. It is a measure of the energy or intensity of the vibration. The greater the amplitude, the stronger the oscillation and the more energy is transported. In physics, the amplitude is often also used to calculate other variables such as the frequency or phase of an oscillation.

What role does damping play in vibrations and how can it be influenced?
Damping plays an important role in vibrations, as it influences the extent to which vibration energy is reduced. It is responsible for the loss of energy within an oscillating system, which leads to a gradual decrease in amplitude.
There are different types of damping, including viscous damping, hysteresis damping and radiation damping. Viscous damping occurs due to the frictional forces acting in an oscillating system. Hysteresis attenuation occurs due to material deformation, while radiation attenuation is caused by the emission of energy in the form of electromagnetic radiation.
The attenuation can be influenced in various ways. One possibility is to increase the viscous damping, for example by using viscous liquids or polymers to increase the frictional forces. Another possibility is to change the stiffness of the system, which can influence the damping properties. Higher stiffness normally leads to lower damping.
In addition, damping can be influenced by the use of damping elements such as shock absorbers or spring-damper systems. These elements absorb the energy of the oscillation and thus reduce the amplitude.
The choice of the appropriate damping method depends on the specific requirements of the system. In some cases, high damping is desired to reduce unwanted vibrations, while in other cases lower damping may be desired to maintain a high vibration amplitude.

How can the period of oscillation of a pendulum motion be calculated?
The period of oscillation of a pendulum motion can be calculated using the formula for the period of oscillation of a mathematical pendulum:
T=2π * √(L/g)
T is the period of oscillation, L the length of the pendulum and g the acceleration due to gravity (approx. 9.81 m/s²).
For a physical pendulum, where the mass of the pendulum is taken into account, the formula is as follows:
T=2π * √(I/mgh)
Where T is the period of oscillation, I is the moment of inertia of the pendulum, m is the mass of the pendulum, g is the acceleration due to gravity and h is the distance between the center of gravity of the pendulum and the suspension.
The exact calculation of the oscillation period can vary depending on the type of pendulum and the given parameters. It is also possible to determine the period of oscillation experimentally by measuring the time the pendulum needs for a certain number of oscillations.

What applications does the concept of resonance have in relation to vibrations and acceleration?
The concept of resonance in relation to vibration and acceleration has many applications in various fields, including:
1. Musical instruments: Resonance is a decisive factor for the sound of musical instruments. When a musician plays a note on an instrument, he creates a vibration that resonates with the natural frequency of the instrument. This amplifies the sound and produces a pleasant tone.
2. Architecture: When designing buildings and bridges, it is important to take resonance phenomena into account. If the natural frequency of a structure coincides with the frequency of an external vibration source, resonance can occur. This can lead to damage to the structure, such as the collapse of the Tacoma-Narrows Bridge in 1940.
3. Electronics: In electronic circuits, resonance can be used to amplify or filter certain frequencies. Resonant circuits, consisting of inductors, capacitors and resistors, can be used to select certain frequencies and suppress others.
4. Medical imaging: In magnetic resonance imaging (MRI), the concept of resonance is used to generate detailed images of the body. The hydrogen atoms in the body are excited to oscillate in a strong magnetic field and generate a signal that is used for imaging.
5. Vibration isolation: Resonance can also be used to reduce unwanted vibrations. By using materials with a natural frequency that is opposite to the frequency of the unwanted vibrations, these can be damped or eliminated.
These are just a few examples of applications of the resonance concept in relation to vibrations and acceleration. There are many other areas in which resonance plays an important role.
