Friction and forces

the 4th list of vocabulary

balanced forces two or more forces whose effects cancel each other out and do not change the motion of the object.
Center of mass point in an object that moves as if all of the object's mass were concentrated at that point.
Force a push or pull
Friction force that acts to oppose sliding in between two surfaces that are touching.
Net force combination of all forces acting on an object
Newton's 1st law states that if the net force acting on an object is zero, the object will remain at rest o move in a straight line with constant speed.
Newton's 2nd law states that an object acted upon by a net force will accelerate in the direction of the force, and that the acceleration equals the net force divided by the object's mass.
Newton's 3rd Law states that forces always act in equal but opposite pairs
Unbalanced Forces two or more forces acting on an object that do not cancel, and causes the object to accelerate.
weight gravitational force between an object and Earth.
