Across
- 2. a vector with all its components equal to zero,
- 3. total distance traveled divided by elapsed time, difference between the ending time and the beginning time,
- 7. 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 ,
- 9. The moving of something from its place or position (the change of place or position),
- 10. rate of change in velocity; the change in velocity over time,
- 13. testable explanation for patterns in nature supported by scientific evidence and verified multiple times by various groups of researchers,
- 15. the degree to which a measured value agrees with an accepted reference value for that measurement,
- 16. length of a vector,
- 18. change in the order of operation introduces the minus sign,
- 20. the degree to which repeated measurements agree with each other,
- 22. state of movement that results from gravitational force only,
- 23. quantitative measure of how much measured values deviate from one another,
- 24. 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,
- 25. science concerned with describing the interactions of energy, matter, space, and time; especially interested in what fundamental mechanisms underlie every phenomenon,
- 26. operations can be performed in any order,
- 27. the location of an object at a particular time
- 28. Occurring or done in an infinitely small amount of time,
- 29. quantity with a dimension of also called quantity of dimension 1 or a pure number,
- 31. using concise language or a mathematical formula, of a generalized pattern in nature supported by scientific evidence and repeated experiments,
Down
- 1. vector written as the vector sum of its components in terms of unit vectors,
- 4. size of a quantity as it relates to a power of 10,
- 5. characteristic or property of an object that can be measured or calculated from other measurements,
- 6. 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,
- 8. 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. mathematical object with magnitude and direction,
- 12. standards used for expressing and comparing measurements,
- 14. the description of motion through properties such as position, time, velocity, and acceleration,
- 17. two vectors with directions that differ by 180°associative terms can be grouped in any fashion,
- 19. the ratio of the uncertainty of a measurement to the measured value, expressed as a percentage,
- 21. a number, synonymous with a scalar quantity in physics,
- 30. units, the international system of units that scientists in most countries have agreed to use; includes units such as meters, liters, and grams significant figures used to express the precision of a measuring tool used to measure a value,
