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. Graph 5 shows a decreasing slope (deceleration) in the negative position direction.

Step2: Analyze Object B

Object B has dots getting farther apart moving right - it's accelerating moving right. Graph 1 shows an increasing slope (acceleration) in the positive position direction.

Step3: Analyze Object C

Object C has dots evenly spaced moving right - it's moving at a constant velocity right. Graph 3 shows a straight - line (constant velocity) in the positive position direction.

Answer:

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