No. The slope on a speed vs time graph tells the acceleration.
A straight line.
Constant speed. Zero acceleration.
It could be a velocity graph or an acceleration graph. If the plot is a straight line it is constant velocity. If the plot is a curve it is acceleration.
The 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.
A graph that shows speed versus time is not an acceleration graph.The slope of the graph at any point is the acceleration at that time.A straight line shows that the acceleration is constant.
If the graph is a straight line, then the slope of the line is the average acceleration of the ball.
On a speed versus time graph, acceleration is represented by the line on the graph. If acceleration is constant, the line cuts through equally between the axis and starts from the zero point.
a horizontal line :)
The slope of a line on a velocity-time graph is acceleration.
Indirectly, yes. If the graph is a straight line there is no acceleration, if the graph is not linear there is acceleration.
No. The slope of the distance-time graph is the change in distance per unit of time - otherwise known as speed. Acceleration is the slope of the speed time graph.
This depends on what the graph represents. If it is a graph of velocity on the vertical and time on the horizontal, then if acceleration is at a constant rate, the graph will be a straight line with positive slope (pointing 'up'). If acceleration stops, then the graph will be a horizontal line (zero acceleration or deceleration). If it is deceleration (negative acceleration), then the graph will have negative slope (pointing down).
acceleration A motion such as the one above further illustrates the important principle: the slope of the line on a velocity-time graph is equal to the acceleration of the object. This principle can be used for all velocity time to determine the numerical value of the acceleration.
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).
