Phaser 2 and Phaser 3 physics difference? [HELP]

Hi!

I’m doing a school assignment about Phaser and I was wondering can someone explain the differences in Phaser 2 and Phaser 3 physics engines?

Phaser 2 has: Arcade, P2 and Ninja physics and I know pretty much the differences in them.

Phaser 3 has: Arcade, Impact, Matter and Multi physics, I guess the arcade is the same as in Phaser 2, but what about impact and matter? Can someone smarter than me explain how these work?

Thank you in advance!
