Across
  1. 2. the rate at which someone or something is able to move or operate.
  2. 5. The total length of the path travelled; is always a positive number; is a scalar; measured with the unit meters (m)
  3. 6. of reference, A defined origin and axes that specify the directions (N, S, E, W; left, right, up, down) in a problem
  4. 7. equations, Equations that tell the relationship between initial and final velocity, displacement, time, and acceleration; are only valid when acceleration is constant
  5. 10. The change in an object’s position from its starting point to its ending point; is a vector that points from the starting point to the ending point; measured with the unit meters (m)
  6. 13. Where an object is located relative to a frame of reference; measured with the unit meters (m)
  7. 14. x-axis; the slope of the line equals the velocity
  8. 15. a line straight or curved that shows relation between two quantities out of which one varies as a result of change in other
  9. 18. speed How “fast” an object travels; the distance an object travels divided by the length of time travelled; is a scalar; measured with the unit meters/second (m/s)
  10. 19. the amount of time between two given points in time
  11. 20. The “steepness” of a straight line on a graph; the change in the y-variable divided by the change in the x-variable; can be positive (uphill), negative (downhill), or zero (horizontal).
  12. 21. speed, The speed of an object at a single moment of time; equals the magnitude of the instantaneous velocity; usually referred to as just “speed”; is a scalar; measured with the unit meters/second (m/s)
Down
  1. 1. A quantity that has both magnitude and direction
  2. 3. the branch of mechanics concerned with the motion of objects without reference to the forces which cause the motion
  3. 4. Graph the x-axis; the slope of the line equals the acceleration
  4. 5. a course along which someone or something moves
  5. 8. velocity, The velocity of an object at a single moment of time; usually referred to as just “velocity”; is a vector; measured with the unit meters/second (m/s)
  6. 9. The change in velocity per unit of time; occurs when an object increases or decreases its speed and/or changes the direction it is moving; is a vector; measured with the unit meters/second2 (m/s2) which is equivalent to “meters per second per second”
  7. 11. vs. Time Graph, A graph of motion with position on the y-axis and time on
  8. 12. vs. time graph, a graph of motion with velocity on the y-axis and time on
  9. 16. A quantity that only has magnitude
  10. 17. velocity An object’s displacement divided by the length of time travelled; is a vector; measured with the unit meters/second (m/s)
