Reference Point

the point from which you measure the motion of an object

Distance

how far an object goes; a scalar quantity

Displacement

the distance and direction measured in a straight line from an object's starting point to its ending point; a vector quantity

Scalar

a quantity for which direction does not matter

Vector

a quantity for which direction must be indicated, by  either a positive or negative value

Speed

how fast an object is moving; a scalar quantity

Velocity

the speed of an object in a given direction; a vector quantity

Acceleration

a change in velocity; speeding up, slowing down, or changing direction

v = d/t

                  Velocity =   Distance

Time

a = Dv/t

acceleration =      (Δ) change in velocity

time
