Defined as the change in position of an object (displacement) per unit of time. Velocity, unlike speed, takes into account the direction of travel relative to a base point.

v = s/t (where v and s are vectors)

Where (using SI units):

v is the velocity of the body in metres per second (ms^-1)

s is the displacement of the body in metres (m)

t is the time taken to travel from the initial point to the final point in seconds (s)

v = s/t (where v and s are vectors)

Where (using SI units):

v is the velocity of the body in metres per second (ms^-1)

s is the displacement of the body in metres (m)

t is the time taken to travel from the initial point to the final point in seconds (s)

1. (One dimension) If you start at point A and travel directly north to point B which is ten metres away, and it takes you five seconds to get there, your velocity will be 2ms^-1 due north.

2. (One dimension) If you travel west for a ten seconds at 1ms^-1, take a break for twenty seconds and then travel for another ten seconds at 1ms^-1, your velocity for the trip will be .05ms^-1 due west.

3. (Two dimension) If you start at point A and travel north at 3kmh^-1 for two hours, and then instantaneously change direction and travel due east for four hours at a speed of 2kmh^-1 to point B, your velocity for the trip is 10kmh^-1 N53°E (53°T)
