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. 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. . 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.. 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. the tensions . T1 and T2 in the strings must satisfy which of the following relations?. (A) Tl = T2 (B) T1 > T2 (C) T1 < T2 (D) Tl + T2 = mg. Answer. As T2 is more vertical, it is supporting more of the weight of the ball. The . What causes an object to start moving, stop moving, or change direction?. UNBANLANCED FORCE. What is a force?. A push or pull. A force is described by strength and direction. The strength of a force is measured in the Newton (N). In-Class Activities. :. Check Homework, if any. Reading Quiz. Applications. . Characteristics of Dry Friction. . Problems Involving Dry Friction. Concept Quiz. Group Problem Solving. Attention Quiz. Friction is the resistance to the sliding, rolling, or flowing motion of an object due to its contact with another object. . When a moving object comes in contact with another object, friction is the opposing force that slows or stops the moving object. . What factors affect (the size of) friction?. Survey says:.
