  3. 9. motion This motion at a constant speed
  4. 13. reasonable for displacement vectors how any two vectors are added.
  5. 15. is a number with one digit to the left of the decimal point and zero or more to the right of it multiplied by a power of ten
  6. 18. A system that interacts with another system to extract and store information about it.
  7. 19. how we represent the velocity of an object points in the direction the object’s motion, and whose magnitude is the object’s speed.

  1. 1. interval , measures the elapsed time as an object moves from an initial position at time to a final position at time
  2. 3. 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
  3. 4. have no uncertainty and when used in calculations do not change the number of significant figures of measured numbers
  4. 5. 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
  5. 6. estimate, A one-significant-figure estimate or calculation such as this estimate of speed
  6. 7. quantity, When a physical quantity is described by a single number with a unit
  7. 10. size or length of a vector
  8. 11. quantity, quantity that has both a size and a direction .
  9. 12. diagram a composite image showing an object’s positions at several equally spaced instants of time
  10. 14. Occurring or done in an infinitely small amount of time
  11. 16. how we graphically represent a vector
  12. 17. An 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
