∙ 13y agoThe problem is that a so-called "velocity-time" graph is really a "speed-time" graph.
A complete description of "velocity" at any point in time includes speed and direction,
but the graph can only show speed, that is, the magnitudeof velocity, vs. time, but
it can't show the direction of the motion. If the direction changes with time, then
that constitutes acceleration, but we can't discern it from the graph.
If the "v-t" graph is a straight line parallel to the time axis, then we know the speed,
and therefore the magnitude of velocity, is not changing. If we also know from some
other source that the motion is in a straight line, then we may say that the acceleration
is zero. But if we have no other information in addition to the graph, we can't reach a
full conclusion regarding the acceleration.

∙ 13y agoIf the velocity-time graph is a straight line parallel to the time axis, it means that the velocity is constant, and there is no acceleration. The value of acceleration in this case would be 0 m/s^2.
If speed is constant, the graph would be a straight line with a constant slope, indicating that the object is moving at a constant rate without acceleration or deceleration. The distance covered would increase linearly with time.

Yes, you can have a situation where an object has a non-zero velocity but zero acceleration. This occurs when the object is moving at a constant speed in a straight line. On a velocity-time graph, this would be represented by a horizontal line at a non-zero velocity value and a flat line at zero acceleration.
A line graph is best suited for comparing the acceleration of automobiles because it can show how acceleration changes over time or across different conditions. This type of graph allows for easy visualization of trends and comparisons between different vehicles or acceleration profiles.
A deceleration graph typically shows a decreasing function where the value of deceleration is decreasing over time. This is in contrast to an acceleration graph, where the value of acceleration is typically constant or increasing over time. The deceleration graph would show negative values as the object slows down.

Straight line at a constant speed = no acceleration
If acceleration is negative the graph looks like a upside U and decreases in value as time continues If acceleration is constant the graph is a straight line (linear) at 0 or whatever the velocity is

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

It tells you the relationship between the X value and the Y value is constant.
To find the time taken to acquire a certain velocity in an acceleration-time graph, locate the point on the graph where the velocity reaches the desired value. Then, find the corresponding time on the horizontal axis at that point. This time value represents the time taken to acquire the initial velocity.
The slope of a graph provides general information about a graph. It tells you how much the y value of the graph increases (or decreases, if the slope is negative) for a given increase in x value. if you look at the general equation of a graph y = a x + b the value "a" represents the slope and the "b" value represents the value of y when x = 0. When the graph is not a straight line, the discussion gets more complicated, however the slope still describes changes in the value of the graph (you have to use calculus for this situation.)
