Vector: A vector is a measurement which has both magnitude and direction.
Displacement: Displacement is a vector with direction pointing from some initial (starting) point to some final (end) point and whose magnitude is the straight-line distance from the starting point to the final point.
Distance: The distance traveled is the length of your actual path.
Velocity: Velocity is the rate of change of displacement with respect to time.
Acceleration: Acceleration is the rate of change of velocity with respect to time.
Resultant: The resultant of a number of vectors is the single vector whose effect is the same as the individual vectors acting together
