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 - diagram of Object A

Object A has evenly - spaced dots, indicating a constant slow speed. On a position - time graph, a constant speed is represented by a straight - line with a small slope. Line 3 has the smallest slope among the non - horizontal lines, so Object A matches line 3.

Step2: Analyze dot - diagram of Object B

Object B has dots that are more spread out than A but still evenly spaced, meaning it has a constant speed greater than A. Line 2 has a steeper slope than line 3 but less than line 1, so Object B matches line 2.

Step3: Analyze dot - diagram of Object C

Object C has the most spread - out evenly spaced dots, indicating the highest constant speed among the three. Line 1 has the steepest slope, so Object C matches line 1.

Answer:

A matches graph: 3
B matches graph: 2
C matches graph: 1
