3.1.1 Kinematics

  • Displacement: the distance of an object from a fixed point in a specified direction

  • Instantaneous Speed: the speed of an object at one specific moment in time

  • Average Speed: the speed of an object over its whole journey.

  • Velocity: the rate of change of displacement of an object

  • Acceleration: the rate of change of velocity of an object

Displacement

    Displacement is a vector quantity, measured in m.

Velocity

    Velocity is a vector quantity, measured in ms-1.
