Position simply describes location,
while displacement refers to a change in position.
Average velocity is displacement
divided by a time interval whereas instantaneous velocity is the velocity
at one instant in time.
Average acceleration is the change
in velocity divided by a time interval whereas instantaneous acceleration
is the acceleration at one instant in time.
Vectors are comprised of a direction
and a magnitude.
Vectors can be used to describe
displacement, velocity and acceleration.
Moving in two or three dimensions
requires an understanding of vector addition (from projectile motion) and
vector subtraction (this module).
