concept summary

2. going left and right, parallel to the horizon
8. The velocity of an object at a single moment of time
10. a quantity that only has magnitude
12. Where an object is located relative to a frame of reference
13. The “steepness” of a straight line on a graph
16. The change in an object’s position from its starting point to its ending point
17. A defined origin and axes that specify the directions in a problem
18. going up and down
19. refers to the general quantity or distance
20. Equations that tell the relationship between initial and final velocity, displacement, time, and acceleration; are only valid when acceleration is constant

1. A graph of motion with position on the y-axis and time on the x-axis
3. An object’s displacement divided by the length of time travelled
4. The speed of an object at a single moment of time; equals the magnitude of the instantaneous velocity
5. is a course along which someone or something moves
6. A graph of motion with velocity on the y-axis and time on the x-axis
7. A quantity that has both magnitude and direction
9. The total length of the path travelled
11. How “fast” an object travels; the distance an object travels divided by the length of time travelled
14. The change in velocity per unit of time
15. is change, or the interval over which change occurs
