CH.26 Vocab

Velocity the speed and direction of a moving object
Force a push or a pull
Net Force combination of all forces acting on an object
Balanced Forces Two or more forces whose effects cancel each other out and do not change the motion of an object.
Unbalanced Forces two or more forces acting on an object that don't cancel, and cause the object to accelerate.
Newtons First Law of Motion states that if the net force acting on an object is zero, the object will remain at rest or move in a strait line with a constant speed
Friction force that acts to oppose sliding between two surfaces that are touching.
Acceleration the change in velocity divided by the time over which the change occurred.
Weight a measurement of force that depends on gravity measures in newtons.
Newton's second law of motion states that an object acted upon by a net force will accelerate in the direction of the force will accelerate equal the net force divided by the object's mass.
Center of mass point in a object that moves as if all of the object's mass were concentrated in that point.
Newtons third law of motion states that forces always act in equal but opposite pairs.
