First 29 words of the document:

It was known that force
causes motion. Newton
clarified this by showing
that in certain
situations, force can
cause acceleration.

First Law
Every object continues
in a state of rest OR
uniform velocity in a
straight line unless
acted upon by an
unopposed (i.e.
resultant) force.…read more

If you kick a ball and no
other force acts on it
(no friction, no weight ­
i.e. assume there is no
gravity) then it will
travel in a straight line
at the speed you kicked
it for ever.…read more

Remember that equal
and opposite forces do
not just act on objects
at rest. They could be
acting on objects
moving at constant
velocity (e.g.…read more

Second Law
The rate of change of
momentum of an object
is directly proportional
to the applied force and
occurs in the direction
of the force.
This can be expressed
mathematically as...…read more
