PPT-Incline and Friction Examples

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. 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. . Friction. Friction is a force that opposes the motion, or tendency of motion, of an object.. Friction is caused . mostly by . the . electromagnetic . interactions of particles within molecules at the surfaces of objects in contact. While these interactions can be rather complex, their combined effects can be reasonably approximated with a decent amount of consistency.. Atwood Lab- due today by 11:59 pm. Newton’s 2. nd. Law Lab- due . Thur. sday . by 11:59 pm. Friction . Lab Wednesday and Thursday. .. Friction Review. Lesson 9. Friction. Friction opposes a sliding motion.. 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.. In-Class Activities. :. Check Homework, if any. Reading Quiz. Applications. . Characteristics of Dry Friction. . Problems Involving Dry Friction.
