U1 One-dimensional Motion Test Review

One-dimensional Motion Test Review

• Magnitude: A number, quantity

• Scalar: A measurement composed of ONLY a magnitude.

• Vector: A measurement composed of BOTH a direction and magnitude.

Definitions:

​Read the y-axis first!!!

Distance: change in position.
--Scalar

Displacement: shortest possible route, including direction.
--Vector
