Khan Academy: Visualizing Multiple Newtonian Path Time Diagrams
Now that we know what path-time diagrams are, let's see what happens when we bring along a friend!

Khan Academy: Starting to Set Up a Newtonian Path Time Diagram
We introduce a graph that's a lot like your good old position-vs-time graph- but with a twist. [7:54]

Khan Academy: Measuring Time in Meters in Minkowski Spacetime
As counterintuitive as it might sound, it will become extremely convenient to use the same units for space and time. Here's how. [4:57]

Khan Academy: Galilean Transformation and Contradictions With Light
Here we'll see how classical physics predicts scenarios that disagree with what we observe in nature. Something's got to give. [8:03]
