How speed of zero would appear on a graph?
-- If the graph displays speed against time, then speed of zero is indicated wherever the graph-line touches the x-axis. -- If the graph displays distance against time, then speed of zero is indicated wherever the graph-line is horizontal. -- If the graph displays acceleration (magnitude) against time, then the graph can tell you when speed is increasing or decreasing, but it doesn't show what the actual speed is.
A straight line on a distance time graph represents what type of speed?
A straight line on a distance/time graph means that the speed is constant. In every unit of time the distance increases by the same amount.
How can you tell if a graph shows an object changing speed?
The answer depends on what variables are plotted on the graph. Without that information it is not possible to answer the question.
Can you tell from a velocity-time graph whether an object is stationary?
If the curve is horizontal, then the speed is constant. If that horizontal graph lies on the x-axis, then the constant speed is zero, and the object is stationary.
How can you tell the difference between a speed and a velocity graph?
Very simply . . . you're not likely to ever see a velocity graph. At least notuntil you get into advanced engineering or science.Velocity is speed and its direction . . . more information than can be displayedon a simple graph.
What happens to a graph of time and distance as speed increases?
The graph of distance vs time increases exponentially as speed increases.
How can you tell by looking at a speed graph what objects speed is the faster?
The point on the graph will be higher (in the normal configuration of such graphs).
How speed of zero would appear on a graph?
-- If the graph displays speed against time, then speed of zero is indicated wherever the graph-line touches the x-axis. -- If the graph displays distance against time, then speed of zero is indicated wherever the graph-line is horizontal. -- If the graph displays acceleration (magnitude) against time, then the graph can tell you when speed is increasing or decreasing, but it doesn't show what the actual speed is.
What does the slope of a wavelength vs period graph tell you?
The speed of sound
When velocity is changing what is happening to the slope on a position versus time graph?
That slope is the 'speed' of the motion. If the slope is changing, then the speed is changing. That's 'accelerated' motion. (It doesn't matter whether the speed is growing or shrinking. It's still 'accelerated' motion. 'Acceleration' does NOT mean 'speeding up'.)
A straight line on a distance time graph represents what type of speed?
A straight line on a distance/time graph means that the speed is constant. In every unit of time the distance increases by the same amount.
Why does speed increase when slope increases?
The slope of the line on a graph of position vs. time is a representation of the speed. When the speed increases, its representation on the graph increases, otherwise it wouldn't be called a "representation". The appearance of a person's hair-do in a photograph is a representation of the length of his hair. If his hair gets longer, then it appears longer in the snapshot. But you wouldn't ask (I hope) ... "Why does his hair get longer when it looks longer in the picture?"
What does straight line on a distance time graph tell you about the speed of an object?
It tells you that the speed of the object is not changing. The speed is represented by the slope in a distance vs. time graph, if slope doesn't change, speed doesn't.
How can you tell if a graph shows an object changing speed?
The answer depends on what variables are plotted on the graph. Without that information it is not possible to answer the question.
How do you tell if a valley glacier is advancing or retreating?
You can tell if it's retreating if it slows it's speed in the glacier. You can tell if it's advancing if it increases in speed.
Does the slope of the line on a speed-time graph tell speed?
No. The vertical coordinate tells the speed in this case. The slow is the derivate of the speed, i.e., the acceleration.
What does the gradient of a line on a distance-time graph tell us about an object?
The gradient of a distance-time graph gives the object's speed.
