Physics 250 Final Exam Review
questions & answers
vectors - answer quantities with magnitude and direction
scalars - answer quantities that have magnitude only
displacement, velocity, acceleration, force, momentum - answer
What are examples of vector quantities?
distance, speed, energy - answer What are examples of scalar
quantities?
multiplied - answer Vectors and scalars cannot be added, but can
be ________.
magnitude, direction - answer Multiplying a vector by a positive
scalar can change the ________ but not the ________.
1. Draw one vector
