A horizontal line parallel to speed axis indicates that the body is moving at a constant speed i.e. it's speed doesn't change with passage of time. The body may have zero or non zero acceleration, but it will always have non zero velocity.
But, that doesn't mean that body's velocity is constant and it is not accelerated. For example in uniform circular motion the speed of body remains constant but velocity changes due to change in the direction of motion. Also there is acceleration towards center of circle called centripetal acceleration which changes the direction of velocity.
For this acceleration a force should act towards the center called centripetal force.
If speed is constant then the force, if present, must act in direction perpendicular to the immediate direction of motion i.e. perpendicular to the tangent drawn at any point on the path of motion.
What else can I help you with?
On a speed-graph a horizontal line shows the change in speed is what?
Constant speedThe graph you described is a speed-time plot. If the line is horizontal, that indicates no change in speed over time. In other words, there is no acceleration (acceleration is zero), since there is no change in speed.
If a graph shows time on the horizontal axis and speed on the vertical axis a straight horizontal line across the graph would indicate what?

constant speed
If a graph shows time on the horizontal axis and speed on the vertical axis straight horizontal line across the graph would indicate what?
The straight horizontal line on the graph says: "Whatever time you look at, the speed is always the same". This is the graph of an object moving with constant speed.
If a graph shows time on the horizontal axis and speed on a vertical axis a straight horizontal line across the graph would indicate?
Constant speed ... zero acceleration.
A graph shows distance on the vertical axis and time on the horizontal axisif the speed is steadily increasing what will the line representing speed look like on the graph?
If a graph shows distance on the vertical axis and time on the horizontal axis, and the speed is steadily increasing, the line representing speed will be a straight line.
What kind of graph shows time on the horizontal axis and speed on the vertical axis a straight horizontal line?
Acceleration
What is the steepness of a line graph equal to its vertical change divided by its horizontal change is referred to as the?
Speed
Does a horizontal line on a distance time graph show constant speed?
No. It shows zero speed. Velocity is distance/unit time. The slope of the line shows change in distance / change in time. Since distance never changes as time changes, the change in distance is zero. Alternatively, the slope of a horizontal line is zero. If zero speed is considered "constant", then yes, it does show constant speed but the speed is zero.
What is on the horizontal axis of a speed graph?
The independent variable, in this case time, is on the horizontal axis of a speed graph.
What is a speed graph?
A speed graph shows how an object's speed changes over time. The horizontal axis represents time, while the vertical axis represents speed. The slope of the line on the graph indicates the acceleration or deceleration of the object.
If a graph shows time on the horizontal axis and speed on the vertical axis a straight horizontal line across the graph would indacate?
that would indicate that the object is at rest (static object) :D
