Key Topics to Revise

1

Scalars and Vectors

  • Scalar quantities have only magnitude (distance, speed, mass, temperature)
  • Vector quantities have both magnitude and direction (displacement, velocity, acceleration, force)
  • Vectors obey triangle law or parallelogram law of addition
2

Vector Operations

  • Multiplication by scalar: λA changes magnitude by factor λ, direction same if λ > 0, opposite if λ < 0
  • Vector addition: Head-to-tail method or parallelogram method
  • Vector addition is commutative: A + B = B + A
3

Resolution of Vectors and Components

  • Any vector can be resolved into components along chosen directions
  • Component vectors: Ax = A cos θ (x-component), Ay = A sin θ (y-component)
  • A = Axî + Ayĵ (in 2D), A = Axî + Ayĵ + Azk̂ (in 3D)
4

Analytical Method of Vector Addition

  • Add vectors by adding their corresponding components
  • If R = A + B, then Rx = Ax + Bx, Ry = Ay + By, Rz = Az + Bz
  • More accurate than graphical method
