That the force that causes the acceleration is not constant.
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).
no because it is possible the object moving make go backwards so the the line will go into the negatives on the graph
A curved line represents changing speed - either acceleration or deceleration - while a straight line indicates that the speed is constant.
The line would indicate motion at a constant speed.
Constant speed (in a straight line) means there is no acceleration.Constant speed (in a straight line) means there is no acceleration.Constant speed (in a straight line) means there is no acceleration.Constant speed (in a straight line) means there is no acceleration.
It means that the object was accelerating or decelerating at least part of the time.
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.
Constant speed ... zero acceleration.
Any curved line will indicate a change in acceleration. Straight lines with slope indicate a steady velocity and straight lines with zero slope indicate a lack of motion.If the X axis (left to right) is for time and the Y axis (up and down) is for speed, it would curve up.
If the graph is a straight line, then the slope of the line is the average acceleration of the ball.
The straight horizontal line on a graph is referred to as the x-axis. The vertical line on a graph is the y-axis.
Indirectly, yes. If the graph is a straight line there is no acceleration, if the graph is not linear there is acceleration.
Ahorizontal line on a velocity vs time graph does not indicate any acceleration because there is no slope. Speed remains constant.
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.
In that case, the graph would be a straight line.In that case, the graph would be a straight line.In that case, the graph would be a straight line.In that case, the graph would be a straight line.

acceleration is zero
