Which of the following most completely describes an object's motion?
Gre4nikov [31]
Hello!

This is a difficultly easy question, mostly because it seems like all of the answers would be right, but if I had to choose one, I would say (D) because this option gives the most detail.

Option A only tells us how fast a car was moving
Option B only tells us the rate the water falls and how fast it is going
Option C only tells how far and not the speed or destination
Option D is correct, it tells us the speed/rate, the destination, and what is moving


Therefore, Option (D) is correct


If this helps, please mark brainliest, have a great day!!
