Newton's First Law CH19S1
Force
Push or Pull
Net Force
Combination of
all the forces
acting on an object
If forces are in the same direction,
they add together
to form a net force
If
two forces
are in the
opposite directions
, then the net force is the
difference between the two forces
, and it is in the
direction of the larger force
Balanced Forces
Two or more forces
exerted on an object
If the forces on an object are
balanced
, the
net force is zero
Unbalanced Forces
Effects don't cancel eachother
If the forces on an object are
unbalanced
, the net force
is not zero
and the
motion
of the object
changes
If the net force acting on an
object is zero
, the object
remains at rest
, or if the object is already
moving
,
continues to move in a straight line with constant speed
Rolling Friction
Needed to make a wheel or tire turn
Friction
The
force
the brings nearly everything to a
stop
Static Friction
Type of friction that
prevents
a object
from moving
when a force is applied.
Caused by the
attraction
between the
atoms
on the
two surfaces that are in contact
Sliding Friction
Slows down an object that slides
