Key Topics to Revise

1

Scalars and Vectors

  • Scalar quantities have only magnitude (e.g., mass, temperature, length).
  • Vector quantities have both magnitude and direction (e.g., displacement, velocity, force).
  • Vectors are represented as directed line segments with an initial point and terminal point.
2

Types of Vectors

  • Zero vector has zero magnitude and no definite direction.
  • Unit vector has magnitude 1 and is used to indicate direction.
  • Equal vectors have same magnitude and direction.
3

Vector Operations

  • Vectors are added using triangle or parallelogram law.
  • Vector subtraction is addition of negative vector.
  • Multiplying a vector by scalar changes its magnitude and possibly direction.
4

Position Vector and Section Formula

  • Position vector of a point P is the vector from origin O to P.
  • Section formula gives position vector of a point dividing line segment in ratio m:n.
  • Midpoint divides segment in ratio 1:1.
