httpwwwaplusphysicscomcourseshonorsdynamicsfrictionhtml Unit 3 Dynamics Objectives and Learning Targets Define friction and distinguish between static and kinetic friction Determine the coefficient of friction for two surfaces. 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. 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.. 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). 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?. Grade Science. What is it?. The force that slows motion between two surfaces that are in contact with each other.. Real life examples. . A baseball player diving into home plate.. Tires on a car can roll freely. Setting up and executing an experiment.. QPOE. 2. Question. Prediction. Evaluate. Observation. Explanation. Knowledge probe. What do you know about . the given question. Investigation plan.
