- 2. a number expressing the central or typical value in a set of data, in particular the mode, median, or (most commonly) the mean, which is calculated by dividing the sum of the values in the set by their number.
- 4. Any object that is being acted upon only by the force of gravity.
- 5. a framework that is used for the observation and mathematical description of physical phenomena and the formulation of physical laws, usually consisting of an observer, a coordinate system, and a clock or clocks assigning times at positions with respect to the coordinate system.
- 6. vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
- 7. the velocity of an object in motion at a specific point in time.
- 10. Another word for speed.
- 11. accurate pictorial representation of data.
- 12. A physics teacher walks 4 meters East, 2 meters South, 4 meters West, and finally 2 meters North. Even though the physics teacher has walked a total distance of 12 meters, her displacement is 0 meters.
Down
- 1. another word for velocity.
- 2. a body falling freely under the influence of the Earth's gravitational pull at sea level.
- 3. the rate of change of velocity of an object.
- 8. a one-dimensional physical quantity.
- 9. a quantity that has both magnitude and direction.
