1. Particle model: A simplified version of a motion diagram in which the moving object is replaced by a series of single points

2. Scalar Quantity: A physical measurement that can be described by magnitude only and has no direction

3. Speed: The distance an object travels per unit of time.

4. Time: The measured or measurable period during which an action, process, or condition exists or continues .

5. Distance: The length of a path between two points.

6. Vector quantity: A physical measurement that contains directional information

7. Velocity: The speed of an object in a particular direction.

8. Displacement: Distance and direction of an object's change in position from the starting point.

9. Time Interval: The time between two events

10. Average Velocity: The total displacement divided by the time interval during which the displacement occurred

11. Instantaneous Velocity: The velocity of an object at some instant or at a specific point in the object's path.

12. Acceleration: The rate at which velocity changes.

13. Average Acceleration: The change in velocity during some measurable time interval divided by that time interval

14. Constant Acceleration: Velocity changing at a constant rate

15. Macroscopic Object: Objects large enough to be visible almost practically with the naked eye, without magnifying optical instruments.

16. Force: A push or pull exerted on an object.

17. Net Force: The overall force on an object when all the individual forces acting on it are added together

18. Velocity Formula: v=d/t Acceleration Formula: a=vf-vi/t Time Interval Formula: t=tf-ti Force Formula: F=ma

19. Units of Velocity: m/s

20. Units of Acceleration: m/s^2

21. Units for Force: N (Newtons)

22. Distance-Time Graph: Line graph used to show the speed of a moving object

23. Velocity Time Graph: A graph that can be used to plot the velocity of an object versus time and to determine the sign of an object's acceleration
