If you are analyzing speed with respect to time, then you are decelerating.
The horizontal line represents that the acceleration is zero or constant speed and the line that slopes downward means that the object is slowing down and it is a negative acceleration.
Line graph.
A straight line, through the origin, sloping up from left to right. The gradient of the graph will be the constant of proportionality.
No. The slope on a speed vs time graph tells the acceleration.
The slope of the graph line or curve.
On a graph of acceleration vs. time, during deceleration the line is below zero. On a graph of speed vs. time, during deceleration the line has a negative slope (sloping downward from left to right).
Slowing down or decelerating
The object is accelerating
If you want the graph to show the acceleration of the ball against time, then the graph is a horizontal line. If you want the graph to show the velocity of the ball against time, then the graph is a straight line sloping downward. If you want the graph to show the height of the ball against time, then the graph is a parabola that opens downward.
The horizontal line represents that the acceleration is zero or constant speed and the line that slopes downward means that the object is slowing down and it is a negative acceleration.
An upward sloping straight line indicates that the object being studied is moving away from the origin and that the component of its velocity in the radial direction is a constant. A downward sloping line indicates it is moving towards the origin. However, neither line says anything about the transverse component of its motion.
This means your velocity is decreasing with time, or in other words, the object is slowing down.
That the object being studied is accelerating in the radial direction.
That depends on what is graphed. If the graph is location versus time, it will be a sloping straight line through the origin. If the graph shows speed versus time, it will be a horizontal line at any height. If the graph shows acceleration versus time, it will be a horizontal line at the height of zero.
That means the speed (the slope of the position-time graph) is decreasing.
Because the expenses are greater than the income.
A motion described as a changing, positive velocity results in a sloped line when plotted as a velocity-time graph. If the acceleration is zero, then the slope is zero (i.e., a horizontal line). If the acceleration is positive, then the slope is positive (i.e., an upward sloping line). If the acceleration is negative, then the slope is negative (i.e., a downward sloping line).
