which graph best represents the motion of an object whose speed is increasing? (1 point)
which graph best represents the motion of an object whose speed is increasing? (1 point)
Answer
Explanation:
Step1: Recall speed - distance - time relation
Speed is the rate of change of distance with respect to time. On a distance - time graph, the slope of the graph represents speed.
Step2: Analyze each graph
- First graph: It has a constant slope, so speed is constant.
- Second graph: The slope is increasing with time. As slope represents speed, an increasing slope means increasing speed.
- Third graph: It has a negative constant slope, so speed is constant but in the opposite direction.
- Fourth graph: The slope is decreasing with time, so speed is decreasing.
