Kinematic Terms

Definitions

Displacement (s) (Distance from O): The relative position of an object with respect to a point (origin, O).

Velocity (v): The rate of change of displacement with respect to time.

Speed: The magnitude of the velocity.

Acceleration (a): The rate of change of velocity with respect to time.

Deceleration / Retardation: Negative acceleration.

Initial: When time, t = 0.

Rest: Not moving, v = 0.
