### Force and Newton's Laws

TermDefinition
force a push or a pull
net force the combination of all the forces acting on an object
balanced forces if the effects of forces on an object cancel each other and they do not change the objects velocity
unbalanced forces the effects of forces on an object do not cancel each other and the object's velocity changes
Newton's First Law of Motion An object in motion (or at rest) will remain in motion (or at rest) unless acted upon by an outside force
friction the force that brings nearly every moving thing to a stop
Newton's Second Law of Motion F=ma; force = mass x acceleration
weight an objects size and gravitational force exerted on the object
center of mass the point in an object that moves as if all the object's mass were concentrated at that point
Newton's Third Law of Motion for every action there is an equal and opposite reaction
static friction the type of friction that prevents an object from moving when a force is applied
sliding friction the force that slows down an object that slides; caused by the microscopic roughness of two surfaces that touch
rolling friction occurs when an object rolls across a surface
