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 getting closer together moving left - it's slowing down moving left. A negative velocity that decreases in magnitude (gets closer to 0) is shown by graph 5.

Step2: Analyze Object B

Object B has dots getting farther apart moving left - it's speeding up moving left. A negative velocity that increases in magnitude is shown by graph 3.

Step3: Analyze Object C

Object C has dots getting closer together moving right - it's slowing down moving right. A positive velocity that decreases in magnitude is shown by graph 4.

Answer:

A matches graph: 5
B matches graph: 3
C matches graph: 4
