Motion Review

3. / elements that have properties of both metals and nonmetals
4. / speeding up, slowing down, or changing direction
6. / chemical bonds that are created when electrons are transferred
8. / variables that scientists want to keep the same throughout the experiment
11. / change that does NOT involve a change in a substance's chemical composition
13. / quantity described by magnitude and direction
15. / if I take the direct route from home to school, it measures my...
17. / if I am always traveling at the same speed, I have...
19. / two or more atoms/molecules physically together but not chemically bonded

1. / a change in position relative to a reference point
2. / quantity described by magnitude alone
5. / total length of path between two points
7. / electrons on the outer shell of an atom that participates in bonding
9. / speed at any moment in time
10. / 30 meters per second Eastbound is an example of this
12. / atom or molecule with a net charge due to a loss or gain of electron(s)
14. / metric system is based on this number
16. / distance traveled in one unit of time
18. / metric base unit used to measure volume
