PPT-3 . 6. Resting Contacts and Friction

3 6 Resting Contacts and Friction Exploration of resting contacts and friction Resting Contacts Resolving a set of contacts Resting Forces A resting contact is a type of contact where the objects involved are moving neither apart nor together. 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 Wedges . & Screws. ENGR B36 - Statics. Pat Aderhold. 11/24/2014. News & Notes. News & Notes. Today’s Agenda. More friction.... Wedges. Screws. Practice Problems on white board. Review / project time. 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.. Friction. Friction is a force that opposes the motion, or tendency of motion, of an object.. Friction is primarily caused by the chemical bonding of molecules at the surfaces of objects in contact (intermolecular forces which are electrical in nature). 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?. 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.. What factors affect (the size of) friction?. Survey says:. Surface texture. Surface material. Surface area. Speed of slide. Mass. Weight. Angle of surface. Normal Force. What is the mathematical relationship between…... . Project guide :. Dr.V. Jai . ganesh. Designation : . Professor. . Project members:. G.Naresh Kumar (11410114032).
