### How to calculate speed from a graph?

If the **graph of** the position in function **from** time is a linear relationship, the **speed calculation** instantaneous is done by determining the slope **of** this **chart**. By drawing the slope **of** this **chart**this is superimposed on the line used for **calculate speed** medium.

### How to calculate the average in km h?

Formula for the **calculation** of speed **medium** To have a speed **kilometer**/**hour**divide the distance into **miles** by time in **hour**. For **calculate** a speed in meters/second, the distance in meters is divided by the time in seconds.

### How to calculate delta t velocity?

What is the **speed** satellite? Otherwise **delta-t** simply refers to the time required to cover the distance; it indeed incorrect to say that v = d/ **you** because **you** designates a date: for example 12:02 p.m. while **delta-t** denotes a difference between two dates (duration) for example **delta-t** = 12:12 p.m. -12:02 p.m. = 10 min.

### What are the different types of charts?

There are several types of charts: bar charts, circle, semi-circle and rectangle charts, curves. It is always necessary to analyze the information of a graph to make a good reading of it and to avoid errors of judgment.

### How to plot a graph?

The plotting of a graph is done from a reading of data pairs (for example, time and temperature). The evolution is then reported on a sheet with two axes (abscissa and ordinate). The points are placed in the form of a cross and connected by hand.

### How to make a graph?

Once the graduations have been made, the pairs of points are placed with crosses by marking their position on the two axes. When all the points are placed, we make a plot by hand and we give a title to the graph. 3. Analysis of the graph its characteristics.

### How to analyze information from a graph?

It is always necessary to analyze the information of a graph to make a good reading of it and to avoid errors of judgment. The graphic representation of economic magnitudes is an essential tool for understanding a given situation or a recorded evolution, by the simplification and the direct reading that it brings.
