Vectors: In the Awesome World of Physics

Today during class we learnt that a vector is composed of a line segment drawn to scale with an arrowhead at the end of it.
  • Collinear Vectors- both in same dimension. Ex. 3cm [N] + 6cm [S] = 3cm [S]
  • Equivalent Vectors- exactly the same. Ex. 2cm [E] + 2cm[E] = 4Cm [E]
  • Non- Collinear Vectors- more than one dimension. Ex. 11m [S] + 5m [W] = ???
Vectors can be added directly if collinear. A negative vector quantity indicates that its direction is actually opposite to that stated and that the sum of two or more vectors is called a Resultant Vector. 


Congratulations! Tessi can go next.
