To determine the direction and magnitude of a vector, you can use trigonometry and Pythagorean theorem. The direction can be found by calculating the angle between the vector and a given reference line, while the magnitude can be found by calculating the length of the vector using the Pythagorean theorem.
A position vector represents the location of a point in relation to a fixed origin, while a displacement vector represents the change in position of an object from its initial position to its final position. In other words, a position vector is static and does not change, while a displacement vector is dynamic and can change depending on the movement of the object.
To add or subtract vectors, you can use the parallelogram rule or the tail-to-tip method. The parallelogram rule involves drawing a parallelogram with the two vectors as its sides and the diagonal of the parallelogram represents the sum or difference of the two vectors. The tail-to-tip method involves placing the tail of one vector at the tip of the other and drawing a new vector from the tail of the first vector to the tip of the second vector.
Vectors can be multiplied by a scalar, which results in a new vector with the same direction but a different magnitude. The scalar multiplication can be represented as c * v, where c is the scalar and v is the vector. However, vector multiplication (also known as cross product) is only applicable in three-dimensional space and results in a new vector that is perpendicular to the original vectors.
Vectors have many real-life applications, such as in physics, engineering, and navigation. In physics, vectors are used to represent forces and velocities. In engineering, vectors are used to represent forces and moments in structures. In navigation, vectors are used to represent the direction and speed of moving objects, such as airplanes or ships.
