Across
- 3. the degree to which a measured value agrees with an accepted reference value for that measurement
- 5. the displacement divided by the time over which displacement occurs under constant acceleration
- 7. acceleration at a specific point in time
- 10. Occurring or done in an infinitely small amount of time
- 12. length of a vector
- 13. two vectors with directions that differ by 180°
- 14. the state of movement that results from gravitational force only
- 17. two vectors are equal if and only if all their corresponding components are equal; alternately, two parallel vectors of equal magnitudes
- 19. the description of motion through properties such as position, time, velocity, and acceleration
- 21. 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
- 22. 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
Down
- 1. two vectors with directions that differ by exactly 90°, synonymous with perpendicular vectors
- 2. the rate of change in velocity; the change in velocity over time
- 4. the location of an object at a particular time
- 6. a number, synonymous with a scalar quantity in physics
- 8. the absolute value of the instantaneous velocity
- 9. the velocity at a specific instant or time point
- 11. change in position
- 15. the total distance traveled divided by elapsed time
- 16. the degree to which repeated measurements agree with each other
- 18. mathematical object with magnitude and direction
- 20. 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
