The video tutorial explains how to add vectors, specifically focusing on the addition of vector U and twice vector V (2V). It begins with an introduction to the concept of vector addition, followed by an explanation of scalar multiplication to determine 2V. The tutorial then demonstrates how to add vectors using the parallelogram method to find the resultant vector. The session concludes with clarifications on the sketching of the resultant vector and addresses any questions.

What is the first step in adding vector U to 2V?

• Determine the direction of U

• Rotate U by 90 degrees

• Double the length of V to find 2V

• Subtract V from U

How do you add two vectors geometrically?

• By placing them tail to tail

• By placing them head to head

• By placing one at the tail end of the other

• By overlapping them completely

What shape is formed when adding vectors U and 2V?

• Triangle

• Circle

• Rectangle

• Parallelogram

What is the resultant vector when adding U and 2V?

• The sum of their magnitudes

• The diagonal of the parallelogram formed

• The difference between U and 2V

• The average of U and 2V

What is the main task when sketching U + 2V?

• Sketch the resultant vector

• Solve for the exact coordinates

• Calculate the angle between U and V

• Find the midpoint of U and 2V
