Question

what does this graph represent?
constant speed
acceleration
not moving

Explanation:

In a distance - time graph, if the distance does not change with time (a horizontal line), it means the object is not moving. For constant speed, the distance - time graph is a straight line with a non - zero slope. For acceleration, the distance - time graph is a curved line (since acceleration implies a change in velocity, and velocity is the slope of the distance - time graph).

Answer:

Not moving
