Resolution of vectors
- Resolution of vectors is the process of breaking a vector down into its component parts.
- This is often useful in physics and engineering problems where vectors are used to represent physical quantities such as velocity or force.
Important points
- Components: A vector can be broken down into two or more components, which are vectors in their own right.
- Orthogonal: Components of a vector are typically chosen to be orthogonal, meaning they are at right angles to each other.
- Magnitude: The magnitude of a component is equal to the length of the component along a particular axis.
- Direction: The direction of a component is specified by its angle relative to a particular axis.
- X-component: The x-component of a vector is the component that lies along the x-axis.
- Y-component: The y-component of a vector is the component that lies along the y-axis.
- Addition: The components of a vector can be added together to form the original vector.
- Trigonometry: Trigonometry is often used to find the magnitude and direction of components.
- Scalar Projection: The scalar projection of a vector is the component that lies along a particular direction.
- Vector Projection: The vector projection of a vector is a vector that lies along a particular direction.
- Parallelogram Law: The parallelogram law states that the vector sum of two vectors is equal to the diagonal of the parallelogram formed by the vectors.
- Triangle Law: The triangle law states that the vector sum of two vectors is equal to the third side of the triangle formed by the vectors.
