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

Back

The magnitude of the resultant vector R can be found using the Pythagorean theorem: R = √(A² + B²), where A and B are the magnitudes of the two vectors.

What is the significance of the angle in vector addition?

Back

The angle between vectors affects the magnitude of the resultant vector; vectors at 0 degrees add directly, while vectors at 90 degrees require the Pythagorean theorem.

Front

What is the component of a vector?

Back

A component of a vector is its projection along the axes of a coordinate system, typically represented as horizontal (x) and vertical (y) components.

What is the direction of a vector?

Back

The direction of a vector is the angle it makes with a reference direction, usually measured in degrees.
