motion	Distance from another object is changing.
reference point	a place or object that can be used to determine if an object is in motion
should reference point be moving	no reference point is stationary
Speed =	Distance/Time
Units to express speed	m/h or m/s or km/min
Acceleration	rate at which velocity is changing
Force	Push or pull exerted on an object
Does every force cause acceleration	no every force does not
Unbalanced forces	cause motion
Balanced forces	do not cause motion
