Ironically, Newton's third law of motion is my favorite among the three laws os motion. Everytime i watched science of stupid philippines and the host is going to mention it, i'll repeat after him.

I always use physics in my math subjects right now lol. And i quite love Physics more than Algebra

An old law of motion riddle...

A fly is flying around in a car. The fly never touches any surface in the car. It only flys around in the air inside the car. The car accelerates. Does the fly slam into the rear window or does the fly continue to fly uninterrupted?

The fly is flying relative to the other movement in the car, so its relative motion stays with those other movement.

It's why when we say we're going to "not move," it's a good thing the cosmos isn't literal like that, or we'd dead in a vacuum while the earth keeps rotating and revolving away from us, as the sun keeps doing the same thing within its neighborhood of a galaxy, within a galaxy that is itself spinning and on the move.

You get an A :)

next question related to what you said... Is there a black hole at the center of galaxies? Does it move?
