Physics · Oscillations and Waves
Students build small pendulums and measure the decrease in amplitude over successive swings. They compare it with diagrams showing ideal, undamped oscillations. What is the primary purpose of this educational activity?
- 1To eliminate the need to study SHM graphs
- 2To understand energy loss due to air resistance and friction and contrast real oscillations with ideal theoretical models✓
- 3To check how quickly students can take repeated readings
- 4To see which group can make the pendulum swing the longest
Correct answer
To understand energy loss due to air resistance and friction and contrast real oscillations with ideal theoretical models
