Force or (potential) energy
for 18-22 and upwards,
Lectures | 18-22 and upwards | 5 years ago | 993 views
Rating:

Classical dynamics uses the concept of force for its solution. On the other hand force in quantum dynamics has no meaning and the concept of potential energy is used instead. The question is, "which one of the concepts is more fundamental?".
