Question

10 sep ask questions the two dot diagrams show an object getting faster (left diagram) and an object getting slower (right diagram). what features about each dot diagram can you use to determine increasing vs. decreasing speed? how do you think speed is defined?

Explanation:

In a dot - diagram, for an object getting faster, the spacing between consecutive dots increases over equal time intervals as speed is the rate of change of position. For an object getting slower, the spacing between consecutive dots decreases over equal time intervals. Speed is defined as the distance traveled per unit of time.

Answer:

For the object getting faster, the increasing spacing between dots over equal time intervals indicates increasing speed. For the object getting slower, the decreasing spacing between dots over equal time intervals indicates decreasing speed. Speed is defined as the distance traveled per unit of time.
