Click For Summary
Arcs in Jacobs ladders form due to a buildup of charge density between the rods, creating a strong electric field. This electric field is sufficient to ionize air molecules, allowing electrons to be ripped off and facilitating conduction. The process is similar to how lightning occurs, which involves a much larger air gap. Understanding this phenomenon can enhance knowledge of electrical conduction and plasma formation. The discussion highlights the fundamental principles of electric arcs and their applications.

When we see an arc between a Jacobs ladder is this because a charge density builds up between the rods and then the E field between the rods is strong enough to rip electrons off the molecules in the air and the start to conduct.

Thread 'Does acceleration affect impact energy vs constant velocity?'

I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
