On position time graph, with position on the y-axis and time on the x-axis, a change in direction is represented by:
|
|
A line that is initially moving upwards, then turns downward
|
|
|
A constantly rising line
|
|
|
A flat, horizontal line
|
|
|
A point at the intersection of the x and y axis
|
|
|
A line that curves sharply
|
Explanation:
Detailed explanation-1: -The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line).
Detailed explanation-2: -time graph reveals pertinent information about an object’s velocity. For example, a small slope means a small velocity; a negative slope means a negative velocity; a constant slope (straight line) means a constant velocity; a changing slope (curved line) means a changing velocity.
