What is sitting inside the car?
The SI unit of distance that would be most appropriate for measuring the distance between two cities.
What is a kilometer?
The shortest distance between two points when you are walking from home to school.
What is displacement?
Displacement after you have traveled 30 km west of your home - turned around and then traveled 10 km east.
What is 20 km west of your home?

What is acceleration?
The acceleration of a sports care that can go from 0 m/s to 28 m/s in 4 seconds.
What is 7 m/s/s?
The speed-time graph would be linear; the displacement-time graph would be nonlinear.
What are the graphs of constant acceleration?
