Unit 1: Kinematics

5. an object that travels through the air and experiences only acceleration due to gravity
6. refers to the interchangeability of order in a function; vector addition uses this property because the order in which vectors are added together does not affect the final sum
8. the magnitude of displacement between two positions
10. the SI base unit for time
12. speed in a given direction
13. ___ relationships can be written as y = mx + b
15. the location of an object at a particular time
17. the study of motion without considering its causes
19. the study of the interactions between matter and energy
20. the rate of change in velocity; the change in velocity over time
21. the SI base unit for mass
22. a quantity that is described by magnitude, but not direction

1. the difference in y-value (the rise) divided by the difference in x-value (the run) of two points on a straight line
2. the SI base unit for length
3. a description of how close a series of measurements are to one another
4. in scientific notation the ___ is always greater than one and less than ten
7. a quantity that is described by both magnitude and direction
9. when dividing you must ___ the exponents
11. the change in position of an object
14. a ratio of equivalent measurements
15. created when graphing quadratic relationships
16. the degree to which a measured value agrees with correct value for that measurement
18. created when graphing inverse relationships
19. scientific notation is written as a ___ of two numbers
20. when multiplying you must ___ the exponents
23. resistance a frictional force that slows the motion of objects as they travel through the air; when solving basic physics problems, this is assumed to be zero
