Net Force Two or more forces exerted on an object and their effects cancel each other out and they do not change the object's velocity. The net force IS zero Balanced forces Two or more forces exerted on an object and their effects of the forces don't cancel, and the object's velocity changes. The net force is NOT zero. Unbalanced Forces According to ______________ if the net force acting on an object is zero, the object remains at rest, or if the object is already moving, continues to move in a straight line with constant speed. Newton's First Law of Motion The force that acts to resist sliding between to touching surfaces. This force brings nearly everything to a stop. Friciton According to _____________ the acceleration of an object equals the net force divided by the mass and is in the direction of the net force. acceleration(in m/s^2)= net force(in newtons) divided by mass(in kilograms) Newton's second law of motion. The measurement of the gravitational force exerted on an object. It is calculated from this equation: w=m(9.8 ms/s^2) (the ^ is the power of or "squared") Weight According to _______ forces always act in equal but opposite pairs. (for every action, there is an equal and opposite reaction) Newton's third law of motion Authoradamah115@me.com ID101937 Card SetChapter 11 Science Vocab (AH) DescriptionMrs. Archer Science Vocab for Chapter 11 Updated2011-09-15T19:13:21Z Show Answers
