Based on the position-time graph data provided, which conclusion can be supported?
A
The object is accelerating uniformly.
B
The object is moving at a constant velocity.
C

D
The object is at rest.
Verified step by step guidance1
Examine the position-time graph: Look for a straight line, which indicates constant velocity. A curved line would suggest acceleration.
Understand the concept of constant velocity: If the graph is a straight line, the slope represents the velocity, which remains unchanged over time.
Consider the implications of a straight line: A straight line on a position-time graph means the object covers equal distances in equal time intervals, indicating constant velocity.
Differentiate between acceleration and constant velocity: Acceleration would be shown by a curve on the graph, while constant velocity is shown by a straight line.
Conclude based on the graph's characteristics: If the graph is a straight line, the object is moving at a constant velocity, supporting the conclusion that the object is not accelerating or at rest.
