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 a constant positive velocity has what kind of characteristics?
The graph of acceleration vs time for an object moving at constant velocity is a straight horizontal line that coincides with the x-axis, i.e. it's the line [ y = 0 ].
Does the horizontal line on the velocity vs time graph indicate a constant and positive acceleration?
Ahorizontal line on a velocity vs time graph does not indicate any acceleration because there is no slope. Speed remains constant.
On a V-t graph how does constant acceleration appear?
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).
Does a softball have a positive or negative acceleration when it is thrown?
positive
If a moving body has no acceleration does it mean that no force is acting on it?
It means there is no net force acting on it. A plane in the air has no acceleration, but it does have forces acting on it. Lift pushes it up Gravity pushes it down Air resistance opposes its movement Thrust provides movement When all these forces are equal the plane will move at a constant velocity. If one of these forces becomes greater the NET force on the plane will no longer be 0 and there will be an acceleration or deceleration. Hope that helps. Another example would be space as there are no opposing forces, if in space once a speed was that speed would be constant until you 1.) decelerated with a force in the opposite direction 2.) accelerated the speed past your current velocity in your current direction 3.) Get caught by some planets gravity and crash to you death (but then this question is the least of your problems)
What is the acceleration of a car that is going at a steady speed of 60 mph?
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.
How does the graph velocity vs the look for something with a constant positive acceleration?
an up ward slopeing straight line
How does the graph of velocity vs. time look for something with a constant positive acceleration?
An upward sloping straight line.
What type of acceleration does a trapezium on a velocity time graph represents?
A period of constant positive acceleration;a second period of zero acceleration; a third period of constant negative acceleration.
Changing velocty and constant acceleration?
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.
The graph of acceleration vs time for something going a constant positive velocity has what kind of characteristics?
The graph of acceleration vs time for an object moving at constant velocity is a straight horizontal line that coincides with the x-axis, i.e. it's the line [ y = 0 ].
What is positive negative and zero acceleration is?
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 velocity is positive and acceleration is zero what happens to an objects motion?
When acceleration is zero, then the object is moving in a straight line with constant speed. (That's the effective meaning of constant velocity.)
Does the horizontal line on the velocity vs time graph indicate a constant and positive acceleration?
Ahorizontal line on a velocity vs time graph does not indicate any acceleration because there is no slope. Speed remains constant.
What would the graph look like on a position verse time plot with constant acceleration?
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.
What is an object that moves with constant position?
An object that moves with constant position will have constant velocity or acceleration. This is said to be moving in positive direction and maintains the position.
A horizontal line on a velocity vs. time graph indicates a constant positive acceleration?
false
