if the speed is zero then the distance versus time line will be horizontal
Standing still or not moving
the slope would be speed.
If you are plotting distance versus time it is a straight line with slope 300000
It tells you that the velocity of the body is not constant. There is acceleration or deceleration.
It is false
Yes it is.
if the speed is zero then the distance versus time line will be horizontal
it is a positive relationship
A horizontal line on a distance versus time graph indicates that the object is not moving. The slope of the line would be zero, meaning there is no change in distance over time.
Straight line
Standing still or not moving
If a line on a distance versus time graph is horizontal, it indicates that the object is not changing its position over time. In other words, the object is at rest and not moving.
Indirectly, yes. If the graph is a straight line there is no acceleration, if the graph is not linear there is acceleration.
A straight horizontal one does.
the slope would be speed.
If the line formed by the graph is straight, the speed is constant. A horizontal line would show the object as stationary.
