⚛️ Physics Quiz 1: Measurement, Units, and Vectors

⚛️ Physics · Quiz 001

Begin with the language of physics: SI units, scalar and vector quantities, displacement, dimensional reasoning, and vector addition.

Learning goalEstablish the measurement language of physics and distinguish scalar quantities from vectors before formal kinematics begins.

FoundationWhich of the following is an SI base unit rather than an SI derived unit?
Need a small nudge?

Ask whether the unit is defined independently or constructed from other SI units.

UnderstandingA student walks 5 m east and then 5 m west, ending at the starting point. Which statement is correct?
Need a small nudge?

Compare the total path traveled with the change from the starting position to the final position.

ApplicationA displacement is 6 m east followed by 8 m north. What is the magnitude of the resultant displacement?
Need a small nudge?

Treat the east and north displacements as perpendicular vector components.

InterpretationWhich ratio of SI derived units has the dimensions of length?
Need a small nudge?

Rewrite each compound unit using standard SI relationships and simplify its dimensions.

ConnectionA hiker walks 300 m east and then 400 m north. Which combination correctly gives the total distance, the magnitude of the displacement, and the displacement direction?
Need a small nudge?

Find path length, vector magnitude, and direction as three separate quantities.
