Vector Addition and Resolution 11th Grade

Front

What is a resultant vector?

Back

A resultant vector is equal to the sum of two or more vectors.

Front

How is a vector often represented in printed materials?

Back

A vector is often represented as an italicized letter in boldface type, called an algebraic representation.

Front

In a vector diagram, which displacement is the horizontal component if the options are 30 km, East; 30 km, West; 40 km, North; 40 km, South?

Back

30 km, West.

Front

What do you need to do if two vectors to be added are at right angles?

Back

You will need to use the Pythagorean theorem.

Front

How do you find the direction and magnitude of a resultant vector?

Back

You can use vector addition methods, such as graphical representation or trigonometric calculations.

Front

What is the Pythagorean theorem used for in vector addition?

Back

The Pythagorean theorem is used to calculate the magnitude of the resultant vector when two vectors are at right angles.

Front

What is the formula for the magnitude of the resultant vector when two vectors A and B are at right angles?

Back

Magnitude = √(A² + B²).

Front

What is the difference between a displacement vector and a resultant vector?

Back

A displacement vector represents the change in position, while a resultant vector is the sum of two or more vectors.

Front

What is the graphical representation of vectors?

Back

The graphical representation of vectors involves drawing arrows to represent the magnitude and direction of vectors.

Front

What is the Law of Cosines used for in vector addition?

Back

The Law of Cosines is used to find the magnitude of the resultant vector when two vectors are not at right angles.
