Question

State the condition under which the distance-time graph of an object is a horizontal line parallel to the axis of time.

Answer 1

Answer:

Considering the x-axis to be the time axis, the plot will be parallel to the time axis (a horizontal line) whenever the velocity of the studied object is zero, i.e.: when the position remains constant throughout the passing of time.

Answer 2

Conditions under which the distance-time graph of an object is a horizontal line parallel to the axis of time;

• Distance-time graph gives the distance traveled by an object or person along with the time taken to travel that distance.
• The slope of the distance-time graph gives the speed of the object or person.
• In this graph the distance is plotted along the y-axis and time is plotted along the x-axis.
• If the graph is a horizontal line parallel to the axis of time, it means the object or the person is at rest.
• In this case, the slope will be zero, which means speed is zero, this again indicates that the object or person is at rest.
