A unit vector is a vector exactly 1 unit (whatever unit you are using) long in a specific direction. If it is going in the positive x direction it is written as shown below. It is read "i hat". the unit vector in the positive y direction would look like "j-hat".
Drag each written vector to the picture of the vector shown in the picture.
Other Answer Choices:
4\hat{i}+3\hat{j}
\hat{i}
\hat{j}
3\hat{j}
4\hat{i}

Play with the phet simulation with 2d vectors. create the situation show below. notice the horizontal and vertical components of the vectors and the resultant vector. play around with using tip to tail addition. give me the resultant \vec{a}+\vec{b} vector in component form. if you type in \hat in the math input, it will give you a box with a hat on top.
