That the force that causes the acceleration is not constant.
A speed graph measures the distance devided over time. Acceleration graph measures the change in speed over time.
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).
A curved line represents changing speed - either acceleration or deceleration - while a straight line indicates that the speed is constant.
An incline represents acceleration, a straight line represents a constant speed and a decline represents slowing down.
Indirectly, yes. If the graph is a straight line there is no acceleration, if the graph is not linear there is acceleration.
If the graph of distance traveled vs. time is not a straight line, it indicates that the object's acceleration is not constant. Acceleration is the rate of change of velocity, so a non-linear distance-time graph suggests that the object's velocity is changing at a non-constant rate, causing a curved graph.
a horizontal 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 constant acceleration
A distance vs time squared graph shows shows the relationship between distance and time during an acceleration. An example of an acceleration value would be 3.4 m/s^2. The time is always squared in acceleration therefore the graph can show the rate of which an object is moving

The graph of distance vs. time suggests constant velocity if it is a straight line, while a curve on the graph implies changing velocity. The graph of distance vs. time squared suggests acceleration, as a linear relationship implies constant acceleration.
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.
It is moving at a constant speed with no acceleration nor decceleration
A distance-time graph is a straight line when the object is moving at a constant speed. This means that the object covers equal distances in equal time intervals. It indicates a uniform motion without acceleration or deceleration.
