Physics

2. concerned with describing the interactions of energy, matter, space, and time to uncover the fundamental mechanisms that underlie every phenomenon.
4. velocity the displacement divided by the time over which displacement occurs under constant acceleration
7. geometric construction geometric construction for drawing the resultant vector of many vectors
10. is a testable explanation for patterns in nature supported by scientific evidence and verified multiple times by various groups of researchers.
11. vector a vector with all its components equal to zero
14. sum resultant of the combination of two (or more) vectors
16. change in position
17. quantity quantity that can be specified completely by a single number with an appropriate physical unit
18. of measurements refers to how close the agreement is between repeated independent

1. acceleration the rate of change in velocity; the change in velocity over time distance traveled the total length of the path traveled between two positions
3. speed the absolute value of the instantaneous velocity magnitude length of a vector
5. vectors two vectors are equal if and only if all their corresponding components are equal; alternately, two parallel vectors of equal magnitudes
6. quantity physical quantity described by a mathematical vector—that is, by specifying both its magnitude and its direction; synonymous with a vector in physics
8. uses concise language to describe a generalized pattern in nature supported by scientific evidence and repeated experiments
9. of magnitude of a number is the power of 10 that most closely approximates it
12. the description of motion through properties such as position, time, velocity, and acceleration distance traveled the total length of the path traveled between two positions total displacement the sum of individual displacements over a given time period
13. the state of movement that results from gravitational force only
15. time the difference between the ending time and the beginning time
