What are common mistakes students make with 2-D vectors?
See explanation below
Common mistakes are not actually very common. This depends on a particular student. However here are a few probable mistakes which a student can make with 2-D vectors
1.) Misunderstand the direction of a vector.
2.) Misunderstand the direction of a position vector
Position vector of any point say
3.) Misunderstand the direction of vector product
Example: The direction of
Note: Two non parallel vectors can be made intersecting by shifting them in their respective parallel directions
There may be other common mistakes as well but above are few of them .
