Across
  1. 4. terms can be grouped in any fashion
  2. 5. two vectors with directions that differ by exactly 90 degrees, synonymous with perpendicular vectors
  3. 7. units the international system of units that scientists in most countries have agreed to use; includes units such as meters, liters, and grams
  4. 10. description, using concise language or a mathematical formula, of a generalized pattern in nature supported by scientific evidence and repeated experiments
  5. 11. units that can be calculated using algebraic combinations of the fundamental units.
  6. 15. A number expressing the central or typical value in a set of data, most commonly the mean, which is calculated by dividing the sum of the values in the set by their number.
  7. 16. two vectors with exactly the same direction angles
  8. 19. the displacement divided by the time over which displacement occurs under constant acceleration
  9. 21. the description of motion through properties such as position, time, velocity, and acceleration
  10. 22. length of a vector
Down
  1. 1. the location of an object at a particular time
  2. 2. The moving of something from its place or position (the change of place or position)
  3. 3. the degree to which repeated measurements agree with each other
  4. 5. A system that interacts with another system to extract and store information about it. It can be a person, a machine, or any other physical system
  5. 6. Occurring or done in an infinitely small amount of time.
  6. 8. the state of movement that results from gravitational force only
  7. 9. An object that is thrown or launched into the air and is only significantly influenced by the force of gravity during its flight, meaning the only force acting on it is essentially gravity after the initial launch; its path is called a trajectory.
  8. 12. testable explanation for patterns in nature supported by scientific evidence and verified multiple times by various groups of researchers
  9. 13. multiplication can be distributed over terms in summation
  10. 14. A ratio that compares two quantities with different units of measurement, essentially expressing how much of one quantity changes with respect to another quantity, often written as a fraction where the numerator represents the first quantity and the denominator represents the second quantity
  11. 17. the total distance traveled divided by elapsed time
  12. 18. a physical quantity that is completely described by its magnitude
  13. 20. the degree to which a measured value agrees with an accepted reference value for that measurement
