A teacher makes a swing pendulum, as shown in the image.
The teacher pulls back and releases ball 1, and students record statements in a table.
1. Ball 1 swings and transfers all of its kinetic energy to ball 2 when it is struck.
2. The kinetic energy moves from one ball to the next until it reaches ball 5 .
3. All of the kinetic energy is lost before it reaches ball 5 .
4. Ball 5 swings in the air to nearly the same height at which ball 1 was released.
5. When ball 1 strikes ball 2 , all of the kinetic energy contained in ball 1 is transformed into sound energy.
