The quantities we write as \(15^{o}C\), \(75 kg\) or \(3 m\,s^{-1}\) are all scalars.

We can't say because there is insufficient information. A direction is required before we can describe the force properly. Displacement is a distance and a direction, eg \(170m\) south. Velocity is a ...

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 ...

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 ...

One of the most important topics taught at the start of introductory physics is the idea of vectors. Students really need proficiency with them if they are to use force and momentum. Just about every ...
