All 23 questions on Forced vibrations and resonance, as a list
- June 2025, Paper 1, Q31 (1 mark): A spring with a spring constant of 50 N m−1 is attached to a rigid horizontal bar. An object of mass m is attached to the bottom of the spring. When the bar is
- June 2025, Paper 3A, Q04.5 (3 marks): Due to damping, only a small number of oscillations occurs after the test tube is released. The student wants to produce a greater number of oscillations for a
- June 2023, Paper 1, Q06.3 (2 marks): Explain what is meant by resonance. [2 marks]
- June 2023, Paper 1, Q06.4 (3 marks): Figure 16 shows a ship moving through continuous waves of wavelength 118 m and velocity 14.2 m s−1. The ship is moving steadily at 8.0 m s−1 relative to the sea
- June 2022, Paper 1, Q05.6 (2 marks): A lamp is used to project shadow images of the block and pendulum bob on a screen. Both shadows appear to move with SHM across the screen. Figure 11 shows the i
