Physics
Graphing Uniform Motion
Motion Diagram: Shows the position of an object at a given time. This allows us to visualize what is happening.
Position Time Graph: Plots time on the horizontal axis and position on the vertical axis
How to Read a Position Time Graph
Three types of slope:Positive slope: The
position of an object is moving further from its origin in uniform motion
How to Read a Position Time Graph
Three types of slope:Zero slope: The position
of the object no longer changes with time (stays in one spot)
How to Read a Position Time Graph
Three types of slope:Negative slope: The
object is moving back towards its origin point
Lets try to interpret a position time graph
-
-
1) Look at the time intervals: What are the time intervals where there is a change in the slope
-
1) Look at the time intervals: What are the time intervals where there is a change in the slope
0s – 10s10s – 15s15s – 40s40s – 55s
-
2) Interpret what is happening at each time interval
Time interval0s – 10s : Moves 60m away from the origin10s – 15s : Stops at 60m away for 5s15s – 40s40s – 55

2) Interpret what is happening at each time interval
0s – 10s : Moves 60m away from the origin10s – 15s : Stops at 60m away for 5s15s – 40s : Moves back towards the origin then
passed it by 40m40s – 55 : turns back towards the origin thenArrives back at the origin
