# URM Test

We have been working through the Uniform Rectilinear Motion (URM) unit. Here is a summary of what you are responsible for in this unit:

 # Objective Need help? Use these video lessons! 1 Add vectors using the component method Intro to Vectors, Representing Vectors, Vector Addition – Components 2 Add vectors using the graphical method Intro to Vectors, Representing Vectors, Vector Addition – Example, Vector Addition – Graphical 3 Choose a reference system suited to the situation Frames of Reference 4 Solve uniform rectilinear motion problems (using Δd = vΔt) Vector Addition – Graphical, Vector Addition – Components, Uniform Motion 5 Differentiate between displacement and distance Position Displacement and Distance, Uniform Motion 6 Draw and interpret diagrams to represent the motion of an object moving with a constant velocity Graphing Position

You will be given the URM equation on your test:

$V_{av}=\frac{\Delta&space;d}{\Delta&space;t}$
