... Balanced forces = a net force of 0 (no change in motion) Unbalanced forces – net force is NOT 0 (produce a change in motion – start, stop, or change speed) SECTION 3 FRICTION: A FORCE THAT OPPOSES MOTION Friction – a force that opposes motion between two surfaces that are in contact Kinetic friction ...

Newtons Laws of Motion Notes
... IV. All objects have a natural tendency to resist changes in motion called inertia. A. Inertia causes objects to remain constant in terms of speed and direction. V. Newton’s 1st Law of Motion A. Law of Inertia B. The velocity of an object will remain constant unless an unbalanced force acts on it VI ...

Circular Motion RS
... 2. What is the direction of the centripetal acceleration of an object in uniform circular motion? Why? 3. A ball is whirled around in a circle. What happens to the centripetal acceleration if the velocity is doubled? 4. If a string breaks that holds a whirling can in it circular path, what causes it ...
