It is radial the velocity in a direction towards or away from a fixed point of reference (the origin) at a given time. The velocity time graph takes no account of motion in a direction across the radial direction.

How do you make an acceleration time graph from the data of a velocity time graph?
take the slope of every change in the velocity time graph and plot it
What is the definition of velocity time graph?
The rate of change in velocity in given time. By Suraj Kumar
What information can be learned from a position-time graph and from a speed-time graph?
A position time graph can show you velocity. As time changes, so does position, and the velocity of the object can be determined. For a speed time graph, you can derive acceleration. As time changes, so does velocity, and the acceleration of the object can be determined.If you are plotting velocity (speed) versus time, the slope is the acceleration.
Is a velocity graph the same thing as an acceleration graph?
Velocity is defined by physicists as both speed and direction, that is to say, if you are moving at 30 feet per second in a northerly direction, that is a velocity. Acceleration means a change in velocity. Physicists consider speeding up, slowing down, or changing direction all to be forms of acceleration; in more everyday usage, acceleration us used to mean speeding up and deceleration means slowing down. So, if your speed increases from 30 feet per second to 40 feet per second, that is acceleration.
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.
How is deceleration represented on a velocity or time graph?
a negative slope this is for my e2020 home boyz
How do you calculate deceleration on a velocity time graph?
It is the downward gradient of the graph.
What is the meaning and formula for deceleration?
Deceleration is the rate of decrease of velocity with respect to time. It is the negative of acceleration. The formula for deceleration is the same as that of acceleration, only that the acceleration is represented as negative. The formula is: - (deceleration) = (final velocity) - (initial velocity) time Therefore, (deceleration) = (initial velocity) - (final velocity) time
On a velocity vs time graph shows what about an objects motion?
It shows the object's acceleration or deceleration.
On a speed time graph what measures acceleration?
deceleration can be measured from a velocity time graph by calculating the gradient of the velocity time graph if the V-t graph was linear. If the v-t graph was a curve then the differentiatial of the equation of the curve will give the deceleration variation with time.
What does a curved line on a distance versus time graph tell you?
It tells you that the velocity of the body is not constant. There is acceleration or deceleration.
How are deceleration and acceleration related?
Acceleration and deceleration are related by their their sign. Acceleration is positive ( increase in velocity with time) and deceleration is negative (decrease in velocity with time).
What is represented by an x intercept on a velocity time graph?
If time is the x-axis as expected then the x-intercept would be zero movement of the velocity.
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 is a velocity time graph in detail?
A velocity time graph is still a velocity time graph - no matter the degree of detail that you look at it.
How do you calculate deseleleration?
Deceleration (not deseleration) is the negative rate of change of velocity over time. Acceleration is [Final velocity - Initial Velocity]/Time. If the final velocity is less than the initial velocity, then the above quantity is negative and is termed deceleration. The instantaneous deceleration is dV/dt, the derivative of the velocity with respect to time. Sometime acceleration and deceleration are defined in terms of speed rather than velocity. This is not correct since it is inconsistent with the laws of motion.
The slope of velocity versus time graph gives?
If your graph shows velocity on the vertical axis and time on the horizontal axis, then the slope of the graph represents the acceleration. More specifically, the slope of the graph at a specific point represents the acceleration at that instantaneous point in time. So if the slope of the graph doesn't change (i.e. the graph is a straight line), then the acceleration is constant and doesn't change over time. In calculus, this is represented as the derivative: The derivative of velocity with respect to time equals the acceleration.
