PPT-Charging by Friction

What rooms in your house and school seem to produce the worst shocks from static electricity What can you do to minimize or eliminate the problem This effect occurs only when electric charges shift from their normal neutral position and is transferred from one object to another. 3 FRICTION The property by virtue of which a resist ing force is created between two rough bodies that resists the sliding of one body over the other is known as friction The force that always opposes the motion of o b Draw a FBD including friction c Solve problems involving friction brPage 2br READING QUIZ 1 A friction force always acts to the contact surface A normal B at 45 C parallel D at the angle of static friction 2 If a block is stationary then the fric ME 225 ; PRINCIPLES OF TRIBOLOGY. PRESENTATION ON. SIDDAPPAJI .B. FRICTION. A force that resists the relative motion or tendency to such motion of two bodies in contact. . Friction always works in the direction opposite from the direction the object is moving, or trying to move. . Wedges . & Screws. ENGR B36 - Statics. Pat Aderhold. 11/24/2014. News & Notes.

Friction is the resistance to the sliding, rolling, or flowing motion of an object due to its contact with another object. . When a moving object comes in contact with another object, friction is the opposing force that slows or stops the moving object. . What factors affect (the size of) friction?. Survey says:.
