1 STATICS ENGINEERING MECHANICSI بسم الله الرحمن الرحيم Friction Friction is a force that resists the movement of two contacting surfaces that slide relative to one another. 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. . 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.. Is F = . μ. N. What is Friction?. Resistive . force caused by two surfaces rubbing against each other. R. esists . an object's motion . - acts . opposite direction of motion . or "intended . motion. Relationship with normal force magnitude. Problem solving involving frictional forces. Lecture 7: Friction. Frictional forces. Frictional force . opposes . motion . or . impending motion relative to a surface. Physics 6A. Prepared by Vince Zaccone. For Campus Learning Assistance Services at UCSB. Friction is a force that opposes the motion of surfaces that are in contact with each other.. We will consider 2 types of friction in this class:. http://www.aplusphysics.com/courses/honors/dynamics/friction.html. Unit #3 Dynamics . Objectives and Learning Targets.
