The position of an object is directly proportional to time.
B
The time taken by an object is independent of its position.

D
The position of an object changes uniformly over time.
Verified step by step guidance1
Understand the concept of a position-time graph: A position-time graph displays how the position of an object changes over time. The x-axis typically represents time, while the y-axis represents position.
Identify the relationship between position and time: When two variables are related in a position-time graph, it often implies a specific type of motion or relationship between these variables.
Consider the options given: Analyze each statement to determine which one accurately describes a relationship between position and time.
Direct proportionality: If the position of an object is directly proportional to time, it means that as time increases, the position increases at a constant rate, resulting in a straight line with a constant slope on the graph.
Uniform change over time: If the position of an object changes uniformly over time, it suggests a constant velocity, which is represented by a straight line on the position-time graph, indicating a linear relationship.
