Flashcards

Resultant Force

The combined effect of multiple forces acting on an object, represented by a single force that produces the same effect.

Displacement

The change in position of an object from its starting point to its ending point, regardless of the path taken.

Resolving Vectors

The process of breaking down a vector into its horizontal (x-component) and vertical (y-component) parts.

Tail-to-Head Method

A graphical method for adding vectors, where the tail of each subsequent vector is placed at the head of the previous vector. The resultant vector is drawn from the tail of the first vector to the head of the last vector.

Magnitude and Direction of a Vector

The magnitude of a vector is its length, representing its strength or size. The direction of a vector is its orientation in space, often described by an angle from a reference point.

Study Notes

Vector Quantities

Vector quantities have both magnitude and direction
Scalars have magnitude only
Vectors are represented graphically by a line with an arrow
The length of the line represents the magnitude
The arrow head indicates the direction of the vector

Addition of Vectors

Collinear vectors are added according to their directions (+ or -)
Non-collinear vectors are added graphically using the tail-to-head or polygon method
The resultant vector has the combined effect of the two (or more) vectors added.

Components of Vectors

Vectors can have components along different directions
For example, a vector in 2D space has components along the x-axis and y-axis.
Resultant vector is obtained by vector addition.

Directions & Notation

Directions use a common compass format
Directions in coordinate planes are often given using angles relative to the x and y axes.
