It means you are going very fast
It means that the object is moving at a high speed in a direction towards or away from the reference point.
When there is a curved line going upwards on a graph it means the distance is increasing
Constant speed. Zero acceleration.
Standing still or not moving
It means that the object in question is moving at a constant speed.If the graph is a straight horizontal line, then the speed is zero.
It means that the speed of the object is constant.
A line that is on a graph
BecAuse that would mean it is going an infinite speed. The slope of a distance time graph is the objects velocity or speed. If there is a line parallel to the distance axis, there is a vertical line. The slope of a vertical line is infinite. It is not possible to go an infinite speed.
No. It means the distance the graph line rises or drops when you move one unit to the righton the horizontal axis.If you're riding along the graph line from left to right in a little tiny car the size of a pinhead,the slope is the description of riding up-hill and down-hill on the line, and how steeply.
