Unit 1 Segment D: Vectors and Scalars A marching band helps us explore the difference between vector and scalar quantities. We also dive into how to use the tip-to-tail method to resolve one and ...

A physical quantity is something that can be measured. Scalar quantities only have size (or magnitude). Vector quantities have size and direction. Speed is a scalar quantity - direction is not ...

Vector quantities have both magnitude and an associated direction. This makes them different from scalar quantities, which just have magnitude.
