    Study Notes

    Scientific Notation

    • The way numbers are written to accommodate values too large or small to be conveniently written regularly
    • a x 10b
      • a is a real number, greater than or equal to 1 and less than 10
      • b is an integer

    Scalar & Vector Quantities

    • Scalar - magnitude but no direction
      • eg. Length, Area, Mass, Temperature, Speed, Distance, Density, Current
    • Vector - magnitude and direction
      • eg. Force, velocity, acceleration, Displacement

    Distance & Displacement

    • Distance (scalar) - measure of magnitude of separation between 2 points
      • How much ground is covered
    • Displacement (vector) - distance moved in a specific direction
      • Change in position
      • eg. 280m = Distance, Displacement
      • 280m → North = Displacement

    Speed & Velocity

    • Speed (scalar) - rate of change of distance
      • m/s
    • Velocity (vector) - rate of change of distance in a specific direction
      • m/s (direction)
