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).
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 does a horizontal line on a velocity time graph show for 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.
What graph of acceleration vs time constant velocity?
When the acceleration of a particle is constant, the velocity will be increasing at a constant rate. This means that the velocity versus time graph will appear with a straight line "slanting up to the right" in the first quadrant. With time on the x-axis and velocity of the y-axis, as time increases, velocity will increase. That means the line will have a positive slope. The higher the (constant) acceleration, the greater the slope of the line. If we take just one example and mark equal units off on our axes, and then assign seconds along the x-axis and meters per second along the y-axis, we can plot a graph for an acceleration of, say, one meter per second per second. Start at (0,0) and at the end of one second, the velocity will be one m/sec. That point will be (1,1). After another second, the velocity will be 2 m/sec owing to that 1m/sec2 rate of acceleration, and that point will be (2,2). The slope of the line is 1, which is the rate of acceleration.
Does a softball have a positive or negative acceleration when it is thrown?
positive
A horizontal line on a velocity vs. time graph indicates a constant positive acceleration?
false
A horizontal line on the velocity vs. time graph indicates a constant positive acceleration.?
false
How would a graph of negative and positive acceleration differ?
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).

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.
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.)
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.
