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. |
