... Friction is resistance between 2 surfaces in contact / resists change Friction does not depend on mass / related to weight It slows things down and makes them stop (can be small/negligible) Can occur doing motion or without motion It acts two ways It usually accompanies a normal force / perpendicula ...

... • Newton’s Second Law of Motion states that when a resultant force acts on an object of constant mass, the object will accelerate. The product of the mass and acceleration of the object is equal to the resultant force. In equation form, this is represened as F = ma • A resultant force is 1 N if the ...

... 1. An isolated object is initially spinning at a constant speed. Then, although no external forces act upon it, its rotational speed increases. This must be due to A. an increase in the moment of inertia. B. an increase in the mass. C. an increase in the angular momentum. D. a decrease in the moment ...

... If a 20 newton block of wood is placed on a wooden surface then the normal force between the block and surface is 20 newtons. It will take slightly more than 8.4 newtons of force to get the block to begin sliding along the surface. Once the block begins to move, the force of friction will immediatel ...
