the car problem in my text uses the unit vector, and the second one doesn't...
how come?
how come?
Unit vectors have a magnitude of 1 and are used to represent the direction of a vector without affecting its scale. This makes them useful for calculations and simplifies the representation of complex vector quantities.
Yes, a unit vector can be used for any type of vector, regardless of its magnitude or direction. It is a standardized way of representing a vector's direction and can be applied to any vector quantity.
Using unit vectors in vector operations simplifies calculations as it eliminates the need for scaling and allows for easier manipulation and comparison of vector quantities.
No, unit vectors can be applied to vectors in any number of dimensions. They are commonly used in 3-dimensional vectors, but can also be used in higher dimensions.
The main drawback of using unit vectors is that they do not retain information about the magnitude of a vector. This means that any calculations involving vector magnitude must be done separately.
