Question

classify the following graphs as moving at constant speed, stopped or increasing speed.

Explanation:

Step1: Graph a (position vs time)

Horizontal line → position unchanged → stopped.

Step2: Graph b (position vs time)

Straight positive slope → constant rate → constant speed.

Step3: Graph c (position vs time)

Curved upward slope → increasing rate → increasing speed.

Answer:

a) stopped, b) constant speed, c) increasing speed
