Introduction to Physics Unit Review

When adding/subtracting vectors using the graphical method, how do you have to arrange the vectors?

• Tip to tip

• Tip to tail

• Tail to tail

When drawing vectors, what corresponds to the magnitude of the vector?

• The thickness of the vector

• The length of the vector

• The direction the arrow representing the vector

What does the opposite/negative of a vector look like?

• A vector with the same magnitude, but going in the opposite direction.

• A vector with a magnitude opposite of the original vector

• A vector directed perpendicular to the original vector
