Verified step by step guidance1
Examine the position-time graph carefully. A position-time graph plots the position of an object on the y-axis against time on the x-axis.
Identify the shape of the graph. If the graph is a straight line, it indicates that the object is moving with constant velocity. If the line is horizontal, the object is at rest.
Consider the slope of the graph. A constant slope (straight line) means constant velocity. A changing slope indicates changing velocity, which could mean acceleration or deceleration.
If the graph shows a curve, analyze whether the curve is getting steeper or flatter. A steeper curve over time indicates acceleration, while a flatter curve indicates deceleration.
Match the observations from the graph with the given options: constant velocity, at rest, decreasing velocity, or accelerating, to determine which description fits the graph.
