Question

end of semester test: physical science a. the position - time graph describes the motion of a moving object. describe the motion represented by each segment of the graph. not moving constant velocity positive acceleration negative acceleration

Explanation:

Step1: Analyze A-B

Horizontal line (constant position) → not moving.

Step2: Analyze B-C

Curved upward (slope increasing) → positive acceleration.

Step3: Analyze C-D

Straight line (constant slope) → constant velocity.

Step4: Analyze D-E

Horizontal line (constant position) → not moving.

Step5: Analyze E-F

Curved upward (slope increasing) → positive acceleration.

Answer:

A-B: not moving, B-C: positive acceleration, C-D: constant velocity, D-E: not moving, E-F: positive acceleration
