Forces

QuestionAnswer
Balanced Forces Two or more forces whose effects cancel each other out and do not change the motion of an object.
Center of mass Point in a object that moves as if all of the object's mass were concentrated at that point.
Force A push or a pull.
Friction Force that acts to oppose sliding between two surfaces that are touching.
Net force Combination of all forces acting on an object.
Newton's First law of motion States that an object is zero, the object will remain at rest or move in a straight line with a constant speed.
Newton's Second law of motion 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 objects mass.
Newton's Third law of motion States that forces always act in equal but opposite pairs.
Unbalance forces Two or more forces acting on an object that do not cancel, and cause the object to accelerate.
Weight A gravitational force between an object and Earth.
