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 . 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 What do you Remember about Friction?. What do you Remember about Friction?. Friction opposes motion. Friction is dependent on the texture of the surfaces. Friction is dependent on normal force. motion. Wedges . & Screws.

To describe different Jewish food, purity and Sabbath Laws with examples. To explain why it was important to keep these laws. To evaluate how difficult it is to keep Sabbath Laws. Why would any religion have “purity” laws to follow?. 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:. EQ: What changes an object’s motion?. Friction and Gravity. What happens when you jump on a sled on the side of a snow-covered hill?. What happens at the bottom of the hill?. Friction and Gravity. Why does the sled’s motion change on the side of the hill and then again at the bottom?. Friction. Unit 2 . Lesson 1. Friction. Friction is a part of everyday life, without it the world would be a very different place. Walking would not be possible, either would driving a car or playing sports. Even sitting on a stool would be difficult.. Notes!. Friction.   . Friction. is a force that o. pposes. motion between . two. surfaces that are touching and creates heat. Friction can be helpful or harmful depending upon the situation..  . What factors affect (the size of) friction?. Survey says:. Surface texture. Surface material. Surface area. Speed of slide. Mass.
