The graph is a line that you can't see because it lies entirely on the x-axis.
The equation of the line is: Y=0
The graph of acceleration vs time for something going at a constant positive velocity would be a horizontal line at zero on the acceleration axis. This is because there is no change in velocity, so the acceleration is constant and equal to zero.
No, a horizontal line on a velocity vs. time graph indicates a constant velocity, not acceleration. An acceleration would be represented by a non-zero slope on a velocity vs. time graph.
A changing slope on a velocity-time graph indicates that the object's acceleration is changing. If the slope is increasing, the acceleration is positive, and if the slope is decreasing, the acceleration is negative. A flat slope indicates constant velocity.
The gradient of an acceleration-time graph represents the rate at which the acceleration is changing over time. If the gradient is positive, it indicates an increase in acceleration, while a negative gradient indicates a decrease in acceleration. A horizontal line on the graph would represent a constant acceleration, where the gradient is zero.
On a graph of speed versus time, where time is plotted along the horizontal (X) axis and speed along the vertical (Y) axis: -- constant speed (zero acceleration) produces a straight, horizontal line; -- constant acceleration produces a straight, sloped line; the slope of the line is equal to the acceleration; -- if the acceleration is positive, the line slopes up to the right (speed increases as time increases); -- if the acceleration is negative, the line slopes down to the right (speed decreases as time increases).

an up ward slopeing straight line
An upward sloping straight line.
A period of constant positive acceleration;a second period of zero acceleration; a third period of constant negative acceleration.
If an object travels with constant acceleration, its speed will change at a constant rate over time. The object's speed will increase if the acceleration is positive, decrease if it is negative, and remain constant if the acceleration is zero.
At a constant speed there is no acceleration. Acceleration describes a positive change in speed meaning to go faster. Deacceleration describes how fast something is slowing down. But at a constant speed of 60mph there is acceleration or deacceleration.
Changing velocity and constant acceleration? Yes. Changing velocity indicates constant acceleration dv/dt = a constant(k) when v=kt. Then dv/dt= dkt/dt= k. the constant k can be positive , negative or zero.
False. A horizontal line on a velocity vs. time graph indicates constant velocity, not constant acceleration. Positive acceleration would be represented by a diagonal line sloping upwards on a velocity vs. time graph.
positive acceleration is when things speed up; negative acceleration is when things slow down; and zero acceleration is when things do not speed up or slow down, this is called constant speed, or no change in velocity.
When acceleration is zero, then the object is moving in a straight line with constant speed. (That's the effective meaning of constant velocity.)
Answer This occurs when an object istraveling in one direction but has an acceleration in the opposite direction, which means it is decreasing in speed. For a given period of time, the speed has decreased. Acceleration is the change of velocity per second. T1 = 5 seconds V1 = 100mph T2 = 10 seconds V2= 50 mph Acceleration = (V2 - V1 ) / (T2 - T1) = (50-100)/(10-5) = -10 ft/sec/sec Positive(+) acceleration means an object will be going faster over an interval of time.
If the constant acceleration is positive, the graph would be an exponential (x2) graph. If there is constant acceleration, then velocity is always increasing, making the position change at an ever increasing rate.
