In simple harmonic motion, which quantity does the symbol A stand for?
AAperture
BAncestry
CAttitude
DAmplitude
Answer & Solution
Correct answer: D. Amplitude
1. The standard displacement expression uses several named symbols.
2. One of them fixes how far the particle goes from the mean position.
3. In the standard symbols, A is the amplitude.
4. The symbol omega is the angular frequency.
