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).
The answer depends on whether the graph is that of speed v time or distance v time.
A period of constant positive acceleration;a second period of zero acceleration; a third period of constant negative acceleration.
A negative slope, called 'a negative gradient' by the intelligent, on a Velocity-Time Graph shows the deceleration of the object. This negative gradient is the positive deceleration and the negative acceleration.
A motion described as a changing, positive velocity results in a sloped line when plotted as a velocity-time graph. If the acceleration is zero, then the slope is zero (i.e., a horizontal line). If the acceleration is positive, then the slope is positive (i.e., an upward sloping line). If the acceleration is negative, then the slope is negative (i.e., a downward sloping line).
Speed can be shown on a graph of position versus time, and acceleration can be shown on a graph of speed versus time.
Acceleration is negative when the object is moving in the opposite direction. on a graph the line would be in the negative quadrant.
Acceleration is negative.
acceleration is the slope of the v t graph... so the acceleration is constant and negative. In other words, the object is slowing down at a constant rate.
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
Deceleration (negative acceleration) is represented by a negative slope on a velocity-time graph.
A negative slope represents deceleration, or negative acceleration.
a correlation on a graph is when the line of best fit is positive, negative or none.
Concave up. "Acceleration is increasing with time" tells us that the derivative of acceleration is positive. Since acceleration is the derivative of velocity, this means that the second derivative of velocity is positive. By definition, having a non-negative second derivative means that velocity is concave up.
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.
to graph not only positive numbers, but negative ones as well
If the x-axis is time and the y-axis is location, the graph will be concave upwards because with positive acceleration, the second derivative of the graph is positive. Another way to put it is that for x-axis as time and the y-axis as location, as you move in the positive x direction, the rate at which y goes up will increase - with the slope becoming more and more vertical.
On a velocity-time graph, increasing speed (acceleration) is represented by a line with a positive slope.
If the speed/time graph slops negatively, that's an indication that the speed is decreasing, i.e. the object is slowing down. The negative slop is also called negative acceleration, since acceleration is the rate of change of velocity.
I believe you are asking how to identify a positive or negative correlation between two variables, for which you have data. I'll call these variables x and y. Of course, you can always calculate the correlation coefficient, but you can see the correlation from a graph. An x-y graph that shows a positive trend (slope positive) indicates a positive correlation. An x-y graph that shows a negative trend (slope negative) indicates a negative correlation.
Positive or Negative........I think...
An object moving with uniform acceleration has a uniform change in velocity over time, and its velocity-time graph will be a straight line with either a positive or negative slope. An object moving with no acceleration has constant velocity, and its velocity-time graph will be a straight, horizontal line with zero slope. Refer to the related link for illustrations.
The line would decrease as the time increased and it would stop once it touched the X axis because you cannot have a negative velocity. This graph would represent an inverse relationship between velocity and negative acceleration/
Quadrant I: x positive, y positive. Quadrant II: x negative, y positive. Quadrant III: x negative, y negative. Quadrant II: x positive, y negative.
The Physical quantity that the slope of velocity time graph show is:negative acceleration otherwise retardation.If the velocity of the body is decreasing then the body is said to have negative acceleration (-ve) or retardation.u>v
False. It has negative acceleration.
