Provide three statements that demonstrate the importance of units when describing motion? I am really confused about this question. I don't know what they are trying to ask.

I think they are asking you about the significance of units in speed (mph, ft/s, etc).

I guess so because it said motion

But I would like a teacher to review it just in case but I don't mind if you help me.

I just want to make sure I got everything right.

Sure, I'm no expert, but that's what I think.

Thank you for help though.

When do think a teacher will help me?

position in meters

speed or velocity in meters/second
acceleration in meters/second^2

Are you sure that is right Damon?

There are a million answers, but if you use those be sure to put them in sentences.

Now you could also show the importance of the difference between inches, centimeters, and miles all of which measure distance but differently.
