1st Law of Motion

Inertia
Motion doesn't change
without an outside force..
Chapter 14 - Force & Motion
Newton's Laws of Motion
2nd Law of Motion

F = ma
This explains how much a
force will change the motion
of an ojbect.
3rd Law of Motion

For every action...
the force will effect the
motion of both of the objects
Homepage       What you need to know
Newton's 3 laws of motion describe all of the motion in the
universe!!  Not only that, but the three laws are easy to
understand and make sense.

His first law describes how an object will act if no outside force
is applied.  It's motion will not change.  This means it is
standing still it won't start moving, and if it is moving it will
continue moving with a constant velocity. (speed & direction)

His second law describes how an unbalanced force will change
the motion of an object.  Both the mass and the amount of
force determine the amount of change in velocity. (remember:
this could be speeding up, slowing down, or changing direction)

His third law says that the force effects both objects involved in
the force (a force is a push or pull between
2 objects).  This
means that both objects will have some change in motion.   
This part can get tricky because we often don't see the change
in the second object because we don't look for it or don't know
what to look for.
There are aspects of these laws that we also need to cover,
the most difficult is acceleration, not just what it is, but the
mathematical formula to calculate it.
