Motion – Distance-Time Graph (Part-5)

Distance-Time graph of a object at Rest

• The distance-time graph of a object at rest is a straight line parallel to the time axis (x-axis).
• The slop of distance-time graph is 0 if the object is at rest.

Distance-Time graph of a object at Uniform Motion

• The distance-time graph of a object moving in uniform motion is a straight line inclined to the time (x-axis).
• Slope: The slope of the graph is the ratio of the vertical change to the horizontal change.
• Slope = Vertical Change/Horizontal Change = Distance Covered/Time take = Speed.
• Slope = Speed (in case of distance time graph).
• The slope of the distance-time graph gives the speed of the object.
• A more steeply inclined distance-time graph indicates greater speed.

Distance-Time graph of a object at Non-Uniform Motion

• Average Speed = Total Distance Covered/Total Time Taken
