Sometimes it is hard to describe the motion of an object.

Luckily, motion can be represented using a graph. Use the video below to look at the basics:

First, there are many different kinds of motion graphs. Each kind of graph needs to be read in a different way

PAY ATTENTION TO THE X & Y AXIS OF EACH GRAPH

This is an example of a distance (position) vs time graph. Remember that speed equals distance divided by time.

Distance vs time graphs can show us speed, but not direction

Velocity vs time graphs shows us if it is getting faster/slower or changing directions (crosses the 0 mark)

Motion graphs will be different depending on the object and how it is represented.

You need to be careful and make sure that you interpret each motion that way it should be
