Grades 9+
Demonstrates conversion of kinetic energy into heat and sound energy during a collision. Consists of a pair of heavy steel balls. When the balls strike against each other with a piece of paper between the balls, the heat causes a hole to appear in the paper. The kinetic energy of the balls upon collision is converted to heat which is…
