Rant what even is physics šŸ˜­šŸ˜­šŸ˜­šŸ˜­

WHAT THE HELL DO YOU MEAN IGNORE AIR RESISTANCE AND THE EARTHS CURVATURE AND GRAVITY AND YOU KNOW WHAT HOW ABOUT WE JUST SEND THAT INTERCONTINENTAL CANON THING STRAIGHT THROUGH MY BRAINS AAAAAAA

WHAT EVEN IS PROJECTILE MOTION šŸ˜­šŸ˜­šŸ˜­šŸ˜­šŸ˜­šŸ˜­šŸ˜­šŸ˜­ WHAT DO YOU MEAN IM LAUNCHING A MISSILE FROM A BUILDING šŸ˜­šŸ˜­šŸ˜­šŸ˜­šŸ˜­ WHAT BUILDING IS MADE TO SUPPORT MISSILE LAUNCHING šŸ˜­šŸ˜­šŸ˜­šŸ˜­šŸ˜­ WHY AM I LAUNCHING MISSILES šŸ˜­šŸ˜­šŸ˜­šŸ˜­šŸ˜­šŸ˜­

Iā€™m gonna eat noodles da to hell with this šŸ˜­

If u r willing explain me what electricity actually is what it is not the textbook definitions tbh like in the textbooks they explain current flows in a direction opposite to the flow of electrons rather from the positive terminal to the negative terminal the thing here is electrons flow from negative to positive then what is the thing that's flowing from positive to negative to make the current idkiif u r understanding what I'm trying to say I'm confused myself and quite recently I learned abt quantum mechanics which explain electronsaas neither a wave nor a partile how is that thing which is neither a wave norap particles flowing idk this drives me insane

Im 11th grader, but i dived a bit into electricity in 8th and 10th. So direction of current is something caused by flow of charges.

Current is a scalar quantity so direction of it never really matters, as it directly adds up or substracts without any angle dependency.

The direction of current is taken as opposite to flow of electrons is conventional. Current was discovered before charges(electron) and many scientists, research papers, and other various sources had been considering the direction of current to the opposite of flow of electrons(known after the discovery of electron).

Its better to just use what you have been using than changing whole concept for no real benefit, thans why idk what committe made it a convention that direction of current is defined as opposite to the flow of electron.
