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 decelerating moving left. This matches a curve that is decreasing in position over time with a decreasing slope. Graph 4 shows such a motion where the object is moving in the negative direction and slowing down.

Step2: Analyze Object B

Object B has dots evenly spaced moving left - it's moving at a constant velocity left. Graph 6 shows a linear decrease in position over time which represents constant - velocity motion in the negative direction.

Step3: Analyze Object C

Object C has dots getting farther apart moving right - it's accelerating moving right. Graph 1 shows a curve that is increasing in position over time with an increasing slope, representing accelerating motion in the positive direction.

Answer:

A matches graph: 4
B matches graph: 6
C matches graph: 1
