2. is the rate of change of velocity.
4. is the time rate of change of position. It is the displacement of a body in a specific time interval. It is a vector quantity.
5. A single vector is usually divided into two vectors
6. are combination of fundamental quantities.
9. refers to the straight-line distance between an object’s initial and final positions, with direction toward the final position.
11. usually come from the measuring instrument or in the design of the experiment itself.
13. result from unpredictable or inevitable changes during data measurement.
15. represents how close or consistent the independent measurements of the same quantity are to one another.
16. refers to the closeness of a measured value to the expected or true value of a physical quantity.

1. described completely by their magnitudes and appropriate units.
3. is a convenient and widely used method of expressing large and small numbers.
7. described by their magnitudes, appropriate units, and directions.
8. This idealized motion of a falling object, which is acted upon only by the force of gravity, is
10. is the process of comparing something with a standard.
12. The sum of two or more vectors
14. is the distance traveled by a body in a given time. It is a scalar quantity.
