摘要:

This paper describes an experiment using a linear air track, which demonstrates the conservation of energy during a collision between an “electron” and an “atom” capable of being raised to an excited state during the collision. The experiment proves that the minimum energy of the incident “electron” required for excitation is larger than the actual excitation energy.
