Graphs are used to show the position, the direction and the speed of an object. To read a graph you must know the x axis is the reference point. The x axis is?
the horizontal (left to right) line on a graph
Graphs are used to show the position, the direction and the speed of an object. To read a graph you must know the y axis is different from the x axis. The y axis is?
the vertical (up/down) line on a graph
On this graph the x axis variable is?
Time
On this graph the y axis variable is?
Distance
An example of data (numbers) that would be used to calculate speed for a moving object would be?
4000 meters divided by 4 minutes
When a line segments y value in the coordinate pair is increasing it creates a line going away from the x axis (reference point) this graph has 3 line segments showing this type of movement
When a line segments y value in the coordinate pair is decreasing it creates a line going towards the x axis (reference point) this graph has 4 line segments showing this type of movement.
All the individual line segments on a distance vs time graph show position/direction/speed of an object's motion. The total distance an object has traveled can be determined from a graph by........
Looking for the data point with the highest y value in the coordinate pair. In this example (3, 12).....12 is the Y value
All the individual line segments on a distance vs time graph show position/direction/speed of an object's motion. The total time an object has traveled can be determined from a graph by........
Looking for the data point with the highest x value in the coordinate pair. In this example (8, 0)....8 is the x value
On a distance vs time graph you can tell an object is moving back towards it's starting point if the line......
returns to the x axis
