No particular reason. They are equally effective.
You have two sides to a bar graph. Each side will have data. Let's say you are graphing a race. On the horizontal axis you could put the names of the racers and on the vertical axis you put the miles. You would then graph the number of miles for each racer in a bar form and color the bars in to show a comparison.
You would use a broken bar graph, when grouping and gathering information. You would use straight, slanted, or vertical lines and showing points with dots. A broken bar graph is just like a line graph.
A pair of numbers that are used to locate a point on a graph is called a ordered pair and is expressed as (x,y) where x is the location horizontally and y is the location vertically. For example the ordered pair (3,5) would be 3 to the right and 5 up away from the origin of the graph (0,0).Is called a ordered pair================ They are called coordinates. They need not be horizontal and vertical distances as suggested by the answer above. They could be polar coordinates which are the angle from the horizontal (anticlockwise), and distance from the origin.
Bar graphs are used to graph frequencies or amounts of data in discrete groups.Bar graphs are used to display data in a similar way to line graphs. However, rather than using a point on a plane to define a value, a bar graph uses a horizontal or vertical rectangular bar that levels off at the appropriate level.
I suggest you go to your math book and look at an example of graphs. Basically, it is a box with labels on the bottom (horizontal axis) of the box representing the items you are graphing and along the vertical axis you will have data. You will put in bars of different colors to represent the data corresponding with the labels. A double bar graph would be two of these.
That would be a bar graph.
You put time on the horizontal axis and distance on the vertical axis.
The straight horizontal line on a graph is referred to as the x-axis. The vertical line on a graph is the y-axis.
constant speed
its not the equation that matters it is how you map it out on the graph, the vertical and horizontal axis are interchangeable. For example if x is the vertical axis and y is the horizontal axis the graph would look different than if y was the vertical axis and x was the horizontal axis. The narrow and wide of a graph depend on the horizontal axis ( how quickly the numbers increase and or how far apart the markers are spaced) ...If the intervals are counted by 5 the graph would be wider than if the intervals were counted by 500.
The given speed is constant for the given period
Constant speed ... zero acceleration.
that would indicate that the object is at rest (static object) :D
yes because horizontal lines are across and vertical lines is up n down
The straight horizontal line on the graph says: "Whatever time you look at, the speed is always the same". This is the graph of an object moving with constant speed.
On the horizontal axis you would probably plot the time. On the vertical axis you could plot displacement, velocity or acceleration.
The horizontal axis would normally be the independent variable and the vertical axis would be the residual.
