describe the motion represented by a horizontal line on a distance time graph

A horizontal line on a distance-time graph shows no change in distance, therefore there is no motion. The object is stationary. ... Constant speed is motion that occurs with the same ratio of distance to time throughout the entire length of the motion.

A horizontal line on a distance-time graph represents pure relaxation, the pinnacle of motionlessness. It's like watching a sloth take a nap on a hammock. Nothing is moving, nothing is changing, it's a glorious display of utter stillness. In other words, it's the mecca of motionlessness. So, grab some popcorn, sit back, and enjoy the mesmerizing motion of nothingness.

A horizontal line on a distance-time graph represents an object that is not moving. It indicates that the object's position remains constant over time, suggesting that it is at rest or has reached a position of equilibrium. This means that there is no change in distance or displacement as time progresses. The slope of the line is zero, indicating no velocity or speed of the object.

A horizontal line on a distance-time graph represents an object at rest or not changing its position. The object is stationary and not moving in any direction.
