Elastic Collision Example Problem Illustration

Elastic Collision Example Problem – Physics Example Problems

Elastic collisions are collisions between objects where both momentum and kinetic energy are conserved. This elastic collision example problem will show how to find the final velocities of two bodies after an elastic collision. This illustration shows a generic elastic collision between two masses A and B. The variables involved […]


About 70% of polybutadiene is used to manufacture tires. (Dean Hochman)

Make Jumping Rubber or Polybutadiene

Interesting Polymer Chemistry Demonstration The “jumping rubber” polybutadiene reaction is a dramatic chemistry demonstration in which chemicals are reacted and sealed into a container, which pops open, shooting out a polymer “snake”. Here is how to perform the demonstration. Jumping Rubber Polybutadiene Materials Jumping Rubber kit plastic or rubber gloves […]
