The 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.

If 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.

How would a graph look if the speed is constant?

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.


For an object that is speeding up at constant rate how would the acceleration vs time graph look?

A line angled upward


Can you have a zero acceleration but non zero velocity.explain with graph.?

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.


What type of graph is best suited for comparing the acceleration of automobiles?

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.


How do you think a graph of deceleration would differ from the graph shown above?

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.

What is the acceleration of car that travels in a straight line at constant speed?

Straight line at a constant speed = no acceleration


In a position vs time graph what does it mean if the position is a negative number?

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

What is a time distance graph?

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

What does the slope of a straight line graph tell you?

It tells you the relationship between the X value and the Y value is constant.


How do you find the time acquired by initial velocity in an acceleration -time graph?

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.


Why use slopes?

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.)
