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 Object A

Object A has dots spaced further apart over time moving left - to - right, indicating increasing speed in the positive direction. This matches line 1 on the graph as line 1 has a positive and increasing slope.

Step2: Analyze Object B

Object B has dots evenly spaced, moving right - to - left, indicating a constant negative velocity. This matches line 5 on the graph as line 5 has a constant negative slope.

Step3: Analyze Object C

Object C has dots very close together, moving left - to - right, indicating a slow constant positive velocity. This matches line 3 on the graph as line 3 has a small positive slope.

Answer:

A matches graph: 1
B matches graph: 5
C matches graph: 3
