Unit 2

8. How far an object is from its starting point, including direction.
9. The study of how things move, without considering forces.
10. When an object slows down or moves in the negative direction.
12. On Earth, the constant acceleration of a free-falling object (~9.8 m/s² downward).
14. A graph that shows how an object’s velocity changes over time.
19. Total displacement divided by the total time taken.
20. How far an object travels, regardless of direction.
21. A series of dots showing an object’s position at equal time intervals to visualize its motion.
23. A change in an object’s position over time.
24. A fixed point used to determine if an object has moved.
25. How fast an object moves; distance divided by time.

1. Moving the same distance every second; speed does not change.
2. Moving at the same speed and in the same direction.
3. When an object speeds up in the positive direction.
4. Motion at constant velocity (no acceleration).
5. Speed in a specific direction.
6. Linear Motion
7. The velocity of an object at a single moment in time.
11. Instantaneous describes one moment; average describes an overall period of time.
13. On a velocity-time graph, the area represents displacement.
15. How quickly velocity changes over time (speeding up, slowing down, or changing direction)
16. The viewpoint from which motion is described or measured.
17. A graph that shows how an object’s position changes over time.
18. A chart showing time and position (or velocity) used to organize motion measurements.
22. On a graph, it shows how fast one variable changes compared to another (on a position-time graph, slope = velocity).
