The state in which one object's distance from another is changing.

• Gravity

• Acceleration

• Speed

• Motion

Answer explanation

Pop! pop! OooO~ Ahhhh!

You can tell Nayeon is in motion because the distance between her arms is changing! You can see this when her hands go "Pop! Pop! Ooo~ Ah."

A Place or object used for comparison to determine whether something is in motion.

• Reference frame

• Motion

• Net Force

• speed

Answer explanation

Obviously, Flash Slothmore is moving because his name is "Flash."

I was joking, jokes. Flash is moving because you can see the files in the back are still. This is called a reference frame!
