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 ...

Today we continue on our journey of understanding motion, direction, and velocity. Continuing in our journey of understanding motion, direction, and velocity... today, Shini introduces the ideas of ...

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

Any vector can be expressed as a sum of a number of other vectors. The vectors which are summed are called the components of the original vector. When you want to add and subtract two dimensional ...
