Concept Summary

2. the starting point of an object
4. when an object slows down, its acceleration is opposite to the direction of its motion
5. when an object changes position
6. the ending point of an object
11. a scalar quantity that refers to "how fast an object is moving."
13. The quantity that tells us how fast an object is moving anywhere along its path
17. a numerical value that describes the steepness of a line
18. a longer length of time can be divided into a number of shorter periods of time, all of the same length
19. the starting point of an object
20. how far out of place an object is

1. when and objects instantaneous speed has the same value throughout its journey
3. an object that has both a magnitude and a direction
7. If the force has a component in the direction opposite to the displacement, the force does negative work
8. a scalar quantity that refers to "how much ground an object has covered" during its motion
9. shows the position of an object at several equally spaced time intervals
10. if the force has a component in the same direction as the displacement of the object, the force is doing positive work
12. a place where someone or something is located or has been put
14. velocity over time
15. a horizontal (flat) line indicates the object is travelling at a constant speed. A straight diagonal line indicates the object's velocity is changing.
16. distance over time
