Exam-style question
Try this first
A pendulum swings with a maximum displacement of 0.5 m. If the acceleration at this point is 4 m/s², what type of motion does it exhibit?.
- A.Uniform motion
- B.Simple harmonic motion
- C.Linear motion
- D.Rotational motion
Model answer
What a good answer should say
- Simple harmonic motion
Explanation
Why this works
The pendulum exhibits simple harmonic motion because its acceleration is directly proportional to its displacement from the equilibrium position and directed towards it. This is characteristic of SHM.
