The problems of the Junior Young Physicists' Tournament, JYPT are selected from the past problems of our parent competition: The International Young Physicists' Tournament, IYPT.

1. Slinky
Suspend a Slinky vertically and let it fall freely. Investigate the characteristics of the Slinky's free-fall motion.

2. Falling Chimney
When a tall chimney falls it sometimes breaks into two parts before it hits the ground. Investigate and explain this.

3. Electric Pendulum
Use a thread to suspend a ball between the plates of a capacitor. When the plates are charged the ball will start to oscillate. What does the period of the oscillations depend on? [Experimental work should only be conducted with teacher supervision]

4. Sound Cart
Construct and demonstrate a device that can be propelled solely by sound. Investigate its properties.

5. Dropped Paper
If a rectangular piece of paper is dropped from a height of a couple of meters, it will rotate around its long axis whilst sliding down at a certain angle. What parameters does the angle depend on?
