In a graph of simple harmonic motion, what does a maximum amplitude represent?.
- A.The point of maximum speed.
- B.The point of maximum acceleration.
- C.The maximum displacement from the equilibrium position.
- D.The average position of the oscillating object.
Model answer
What a good answer should say
- The maximum displacement from the equilibrium position.
Explanation
Why this works
The evidence shows that the amplitude is defined as the maximum distance from the equilibrium position in SHM. This implies that the amplitude directly relates to the energy stored in the system, leading to the conclusion that a larger amplitude indicates greater potential energy at maximum displacement.
