In the graph which region shows nonuniform positive acceleration?
AB
How would a graph look if the speed is constant?
That would depend on the type of axes. If it is an acceleration vs. time graph, then there would be a continual reading of 0m/s/s acceleration, and the graph would be a straight line indicating 0m/s/s at all times. If it is a velocity vs time graph, then there would be a constant value of velocity at all times. If it is a displacement vs time graph, there would be a straight, continuously increasing line.
On a velocity vs time graph shows what about an objects motion?
It shows the object's acceleration or deceleration.
The graph at the top of the second column of page 122 shows a condition in which there is what?
no acceleration
The slope of velocity versus time graph gives?
If your graph shows velocity on the vertical axis and time on the horizontal axis, then the slope of the graph represents the acceleration. More specifically, the slope of the graph at a specific point represents the acceleration at that instantaneous point in time. So if the slope of the graph doesn't change (i.e. the graph is a straight line), then the acceleration is constant and doesn't change over time. In calculus, this is represented as the derivative: The derivative of velocity with respect to time equals the acceleration.
In an acceleration graph showing speed versus time a straight line shows the acceleration is?
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.
What kind of graph shows time on the horizontal axis and speed on the vertical axis a straight horizontal line?
Acceleration
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.
What shows acceleration an a speed time graph?
The slope is the acceleration. Acceleration is the time derivative of velocity.
In the graph which region shows nonuniform positive acceleration?
AB
What type of graph can you use to analyze the accelerates?
A line graph. It shows both the acceleration and the deceleration.
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?
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.

It shows the object's acceleration or deceleration.

Infer the motion of a car whose speed-time graph shows a horizontal line followed by a straight line that slopes downward to the bottom of the graph?
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.
What is the importance of uniform acceleration graph in physics what is instantaneous velocity?
The slope of a velocity-time graph that shows uniform acceleration is the actual acceleration. Instantaneous velocity is the velocity of a body at a particular moment in time.
