To determine which direction an object is moving on a velocity-time graph we should see whether the graph is above or below the x-axis at that time.

If the velocity - time graph is above the x-axis, the velocity is positive. A positive velocity means the object is moving in the positive direction (e.g., forward). If the graph is below the x-axis, the velocity is negative, and the object is moving in the negative direction (e.g., backward). This is the correct way to determine the direction of motion of an object at a particular time.

Option A, Determine the area between the graph and the x-axis up to that time

The area between the graph and ...
