Today, we couldn’t go outside to do whatever we suppose to because of the weather, so we were staying inside to learn unit notation.
The following list is what we were doing in class.
1. Vector Addition homework check
2. We took notes on unit vector
- Summary: A unit vector is a vector whose length of 1 (the unit length). A unit vector often denoted by a lowercase letter.
- Unit vector expression: (Xi + Yj)unit.
To find X and Y: X=Rcosθ, Y=Rsinθ, R is the length of vector.
For more information:
I can’t explain the concept properly, so this video may help you understand better.
3. After that, we did the pair check on unit vector and turned in.
4. Then we continued with the lab manual page 9, and I believe that you can find direction on the paper.
5. Homework is to finish the lab page 9, and unit vector notation worksheet.
