Question

the graph below shows the change in position over time for a 100 g weight as it falls. which statement below best describes the motion of the 100 g weight? the weight positively accelerates as it falls. the weight falls at a constant speed. not enough information to answer the question. the weight negatively accelerates as it falls.

Explanation:

Step1: Analyze the position - time graph

In a position - time graph, the slope of the graph represents the velocity. If the slope is increasing, the velocity is increasing.

Step2: Determine the nature of acceleration

Since the slope of the position - time graph of the falling weight is increasing (the curve is getting steeper as time increases), the velocity of the weight is increasing. When velocity increases, the acceleration is positive.

Answer:

A. The weight positively accelerates as it falls.
