Physics

5. a body falling freely under the influence of the Earth's gravitational pull at sea level.
8. accurate pictorial representation of data.
9. the rate of change of velocity of an object.
10. Another word for speed.
11. a quantity that has both magnitude and direction.
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.

1. another word for velocity.
2. Any object that is being acted upon only by the force of gravity.
3. a one-dimensional physical quantity.
4. 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.
5. 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.
6. the velocity of an object in motion at a specific point in time.
7. vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
