Question

a student compares the motion of two objects, a and b, that have different accelerations. what can be concluded about the velocity of the two objects from the graphs? object a object b constant velocity increasing velocity object a object b decreasing velocity constant velocity object a object b increasing velocity decreasing velocity object a object b decreasing velocity increasing velocity

Explanation:

Step1: Recall velocity - distance - time relationship

The slope of a distance - time graph gives velocity.

Step2: Analyze Object A's graph

The slope of Object A's distance - time graph is increasing. As slope = velocity, its velocity is increasing.

Step3: Analyze Object B's graph

The slope of Object B's distance - time graph is decreasing. So its velocity is decreasing.

Answer:

Object A: increasing velocity, Object B: decreasing velocity
