Perfectly Elastic Collision - Real World Examples

AI Thread Summary

A perfectly elastic collision is defined as a collision in which no kinetic energy is lost, meaning there is no sound or friction involved. This type of collision is primarily observed at the atomic level, such as in the interactions between gas particles. While perfectly elastic collisions are idealized concepts, they do not occur in the macroscopic world due to various energy losses. The discussion highlights the distinction between perfect and elastic collisions, emphasizing that perfect elasticity is a theoretical construct. Overall, perfectly elastic collisions are largely theoretical and not found in everyday experiences.

What is a perfectly elastic collision?

Does it exist in the real world?

Perfect elastic collision is a collision where no kinetic energy is lost during the collision (so there is no sound and no friction during the collision). This occurs on the atomic level (for example gas particles collide basically elastically)

i thought that's only an elastic collision?

Thread 'Linear generator prototype'

i want to just test a linear generator with galvanometer , the magnet is N28 and the wire (Cu) is of 0.6mm thikness and 10m long , but galvanometer dont show anthing , The core is PLA material (3d printed) The magnet size if 28mm * 10mm * 5mm

Thread 'Mechanism of Energy Conservation in Zero-Amplitude Sum of EM Waveforms'

Assume that this is a case where by sheer coincidence, two sources of coherent single-frequency EM wave pulses with equal duration are both fired in opposing directions, with both carrying the same frequency and amplitude and orientation. These two waves meet head-on while moving in opposing directions, and their phases are precisely offset by 180 degrees so that each trough of one wave meets with the crest of the other. This should be true for both the electric and magnetic components of...
