an action that is able to change motion is called
force
the only time that the net force on an object is zero is when all of the forces are
balanced
the tendency of an object to resist a change in motion is called
inertia
in order for a net force on an object to change the object's motion, the forces must be
unbalanced
force
only action that has the ability to change motion an not be started or stopped without force
force is used to
increase or decrease speed and change direction of the object
newton's first law is the law of inertia
an object at rest will stay at rear and an object in motion will rest and an object in motion will stay in motion at the same velocity unless acted on by an unbalanced force
what inertia mean?
property of an object that resists a change in its motion comes from mass, more mass = more inertia
what unbalanced forces mean?
resoult in a net force on an object that can cause changes in motion. net force = 0
what cause motion?
multiple force = net force
