A couple of very simple questions about vectors and scalars
I am a sophomore engineering student at The University of Tennessee (Go Vols!) and I am currently enrolled in Calc 3. I feel like I understand the more advanced concepts but struggle with the simpler stuff (like a person reading with no phonics, simply memorization). Therefore I feel like my basic knowledge needs to be boosted... hopefully the answers to these questions will help!
1. Is a scalar the same thing as a vector's magnitude?
2. Can a vector be made from a scalar?
3. Additionally, how (in written notation) is it possible to tell the difference between the two? Like is one wrapped in abs value bars or what? Just a little confused about the context of all of this.
Thank you, everyone!
