Kreisbewegung, Schwingungen und Wellen: structured theory, worked examples, answered practice, and a mastery checklist for German Gymnasium Klasse 10.
单元
练习前按清晰顺序掌握本章核心概念。
A wave transfers energy and information without net transfer of matter. Distinguish amplitude, wavelength, period, and frequency.
The relation v = fλ connects the medium and the oscillation. At a boundary, source frequency stays fixed while speed and wavelength may change.
Use the normal, angles, and wavefronts. Superposition adds displacements without permanently changing the component waves.
For “Kreisbewegung”, start from an observation or model, define quantities and units where relevant, and separate the changed factor from the measured outcome. Support the conclusion with data and state the test's limitations.
For “Zentripetalkraft”, start from an observation or model, define quantities and units where relevant, and separate the changed factor from the measured outcome. Support the conclusion with data and state the test's limitations.
For “Schwingungen”, start from an observation or model, define quantities and units where relevant, and separate the changed factor from the measured outcome. Support the conclusion with data and state the test's limitations.
For “Wellen”, start from an observation or model, define quantities and units where relevant, and separate the changed factor from the measured outcome. Support the conclusion with data and state the test's limitations.
For “Frequenz”, start from an observation or model, define quantities and units where relevant, and separate the changed factor from the measured outcome. Support the conclusion with data and state the test's limitations.

A wave has frequency 4 Hz and wavelength 2 m. Find its speed.
v = 8 m/s
Before calculating, explain the key idea from “Kreisbewegung” and which conditions must be checked.
The answer should show not only which rule is used for “Kreisbewegung”, but also why it is valid here.

八道分层练习，从基础熟练到考试应用。请先独立完成，再查看提示或答案。
A wave has f=9 Hz and λ=1.5 m. Find speed.
v=fλ.
v=13.5 m/s.
Structure a solution for “Zentripetalkraft”: givens, SI units, law, substitution, and interpretation.
State the law before substituting numbers.
A full solution states symbols/units, selects a valid law for “Zentripetalkraft”, shows substitution and calculation, and interprets the result.
Identify three uncertainty sources in measuring “Schwingungen” and improve each one.
Consider instrument resolution, reaction time, repeats, and controls.
A full response links each specific error source to a targeted improvement and identifies random or systematic impact.
Plan a suitable graph for “Wellen” data and explain how to obtain a gradient or relationship.
Put the independent variable on x and dependent variable on y.
A full response labels axes/units, uses a suitable scale and best fit; gradient uses a large triangle and is interpreted with units.
Check whether a result for “Frequenz” is sensible using units, order of magnitude, and a limiting case.
A check should not merely repeat the same calculation.
A full check confirms dimensions/units, compares expected magnitude, and tests behaviour when one variable becomes very small or large.
Connect “Wellenlänge” to energy conservation or a force/field model and justify the choice.
Define the system and interactions.
A full response defines the system, describes transfer or interaction, applies the appropriate model, and states losses or limitations.
Write a multi-step exam response about “Wellengeschwindigkeit” with calculation and evaluation.
Separate givens, model, calculation, result, and evaluation.
A full response includes an appropriate diagram/model, laws, algebraic rearrangement, SI substitution, suitably precise result, and evaluation of assumptions.
Compare two methods for investigating “Kreisbewegung” and select the more reliable using criteria.
Use accuracy, repeatability, control, and safety.
The choice must use at least three comparable criteria and acknowledge one trade-off or limitation.
