D1-43: INERTIAL FORCES - BALLS IN ROTATING JARS
Additional Info
- ID Code: D1-43
- Purpose: Demonstrate inertial forces in bodies submerged in air and in water.
- Description: On one side of the arm a ping-pong ball is suspended by a string from the top of a jar filled with air. On the opposite side of the arm a ping-pong ball is attached by a string to the bottom of a jar filled with water. When the arm is rotated, the ball in the air jar moves outward and the ball in the water jar moves inward.
- Availability: Available
- References: REFERENCES: (PIRA 1D52.30) See Demonstration Reference File for several interesting articles.
- Loc codes: D1
