## MTH622: Vectors and Classical Mechanics

A vector is an object that has both magnitude and direction. Geometrically, we can imagine a vector as a directed line whose length is the magnitude of the vector and with an arrow indicating the direction. MTH622 Handouts pdf

#### Scalar Point Function

If to each point (𝑥, 𝑦, 𝑧) of a region R in space there corresponds a scalar 𝜑(𝑥, 𝑦, 𝑧), then 𝜑 is called a scalar point function in R.  Scalar field is a function defined on space whose value at each point is a scalar quantity The set of all values of scalar point function 𝜑 in R together forms a Scalar field.

#### Vector Point Function

If to each point (𝑥, 𝑦, 𝑧) of a region R in space there exists a unique vector 𝐴⃗ (𝑥, 𝑦, 𝑧), then 𝐴⃗ is called a vector point function in R.  A function of a space whose value at each point is a vector quantity is called a vector field. Mathematically, we can write it as 𝐴⃗=𝐴⃗ (𝑥, 𝑦, 𝑧) =𝐴1 (𝑥, 𝑦, 𝑧)+ 𝐴2 (𝑥, 𝑦, 𝑧) +𝐴3 (𝑥, 𝑦, 𝑧) The set of all values of 𝐴⃗ in R constitute a vector field.

#### Chasle’s Theorem

In kinematics, the Chasles theorem or Mozzi-Chasles theorem states that the most general displacement of a rigid body can be produced by displacement along a straight line (called its helical axis or Mozzi axis) followed by (or preceded by) a rotation about an axis parallel to that straight line.
