Question

consider the dot diagrams for objects a, b, and c. the arrow represents the direction of motion. match the motion of objects a, b, and c to one of the lines on the graph. numbers can be used only one time. a matches graph: - b matches graph: - c matches graph: -

Explanation:

Step1: Analyze dot - diagrams

In a position - time graph, the slope represents the velocity. The more spread out the dots in the dot - diagram (for equal time intervals), the greater the velocity. Object A has the fewest dots and is most spread out, so it has the highest velocity. Object C has the most dots and is least spread out, so it has the lowest velocity. Object B is in between.

Step2: Match with graphs

The steeper the line in a position - time graph, the greater the velocity. Line 1 has the steepest slope, line 3 has a moderate slope, and line 6 has the least steep slope.

Answer:

A matches graph: 1
B matches graph: 3
C matches graph: 6
