What else can I help you with?
Do bar graphs start at the number zero?
A bar graph's data doesn't always start with zero but the scale on the y axis should. If you are not going to start the scale with zero then you have to put a squiggly line at the bottom to show that you skipped this space.
What are the units on the vertical axis of a line graph?
The units are whatever you make them! It helps, though if the units are the same on the x-axis (horizontal axis) as well. Unless of course you are skipping from zero to some large number before you start your graph. Anyway, you can make each line one unit, or you can make each line 5 units, or whatever you want! Depends on what you're graphing, but usually for a straight line, you use units of 1
What is a broken scale bar graph?
A broken scale is a symbol used when a scale on the graph starts at a big number. It can be used on the x and y axis. It looks like the number 3 but with straight lines so it is a zig-zag and is places ON the axis line eg if the scale on the y axis starts at 324, you would write zero then the broken scale ON the line then 324.
What does the squiggly line mean when it starts at zero on a graph?
it means that from zero to the first number next to the graph is not in the same order as the other numbers. for example it might me 0,10,15,20,25. there will be a squiggly line after 0 because 0+5 is not 10 and the pattern here is adding 5 each time. hope this helps:)
Why do bar graphs have to start at zero but line graphs do not?
line graphs show a change over time
Why the straight line in the graph doesn't start from zero?
Unless it is a direct proportion, the straight line does not have to start from zero.
For motion along a straight line a horizontal line on a speed over time graph indicates graph indicates that what is zero?
For motion at constant speed along a straight line, the acceleration is zero.
If a straight line graph has a gradient of zero it must be horizontal?
120?
What does it mean when a distance-time graph is straight line?
It means that the object in question is moving at a constant speed.If the graph is a straight horizontal line, then the speed is zero.
To create a line graph do you have to start off at the zero?
Yes
What does a straight line mean in a distance time graph?
Constant speed. Zero acceleration.
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 will be graph if an asymptote of it touches at three points?
if it touches at three points it is a straight line. Since it is also an asymptote, it will be a straight horizontal line (zero slope)
If an objects velocity time graph is a straight line parallel to the taxis what can you conclude about the objects acceleration?
If an object's velocity-time graph is a straight line parallel to the time axis, then the object's acceleration is zero. This means that the object is moving at a constant velocity.
What is the nature of velocity time graph for uniform retardation?
The velocity-time graph for uniform retardation is a straight line with a negative slope. The velocity decreases uniformly over time until it reaches zero. The area under the graph represents the displacement of the object.
If a graph shows time on the horizontal axis and speed on a vertical axis a straight horizontal line across the graph would indicate?
Constant speed ... zero acceleration.
Suppose you plot the distance traveled by an object at various times and you discover that the graph is not a straight line what does this indicate about the object acceleration?
If the graph of distance traveled vs. time is not a straight line, it indicates that the object's acceleration is not constant. Acceleration is the rate of change of velocity, so a non-linear distance-time graph suggests that the object's velocity is changing at a non-constant rate, causing a curved graph.
