U3 Physics Test Study Guide
complete with verified
solutions already graded A+
(solved & updated)
What is a vector? - answer a quantity that has both magnitude and
direction
How do you represent vectors? - answer use arrows where point
represents direction and length represents magnitude
What is a vector diagram? - answer diagrams that depict the direction and
relative magnitude of a vector quantity by a vector arrow
What is a collinear vector? - answer A arrow that points in a straight line,
it can either point in the same or opposite directions.
What are the rules when solving for the resultant vector? - answer 1.
define scale and direction
2. draw and label
3. add or subtract
4. units must be the same
5. your final value depends on your vector drawing
What is trigonometry? - answer The study of triangle measurement
What are the trigometic ratios? - answer sine ➝ sinθ
cos➝cosθ
tan➝ tanθ
