PPT-Friction Force 12-1 Learning Objectives

I can explain what causes friction and how it affects the motion of an object I can identify and describe the four types of friction I can give examples of the four types of friction Forces Friction. 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. . Ms. King desk. BOARD. BLACK . DESKS ONLY:. Jamya, Cooper, Breonna, Matthew, . Sapphira. , Justice, Christian. Kenneth. Torien. Donovan. Davon B. Destiney H. Dearell. Terronda. Kiana. Chiarrah. Tayia. Is F = . μ. N. What is Friction?. Resistive . force caused by two surfaces rubbing against each other. R. esists . an object's motion . - acts . opposite direction of motion . or "intended . motion. 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:. is a pull or a push.. Force. The unit of measure for force is . Newton (N). . . . . English scientist.. . (1643 – 1727) . A force that opposes motion between two surfaces that are in contact.. Causes a moving object, such as a ball, to slow down and stop.. Occurs because the surface of any object is rough (microscopic hills and valleys). http://www.aplusphysics.com/courses/honors/dynamics/friction.html. Unit #3 Dynamics . Objectives and Learning Targets. Define friction and distinguish between static and kinetic friction.. Determine the coefficient of friction for two surfaces.. 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. Weight. Angle of surface. Normal Force. What is the mathematical relationship between…... A. nswer 9/7/16. A hiker’s velocity begins at 1.8 m/s uphill and changes to 1.5 m/s uphill. How do you know that the hiker has a negative acceleration?. 4 Types of Friction. The 4 types of friction are: . The amount of friction depends on...... Surface Roughness. Forces pushing the two surfaces together.. Types of Friction. https://app.discoveryeducation.com/player/view/assetGuid/72E28A59-0EAB-4EC9-A097-365513460023. gawas. . . Sonam. . gosavi. Neekita. . Bhowar. . FRICTION. Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.. Friction k a is usually greater than the coefficient of static friction s b usually equals s c is usually smaller than s d equals the applied force that exceeds the maximum static force c 2 The purpos 1. STATICS. (ENGINEERING MECHANICS-I). بسم الله الرحمن الرحيم. Friction. Friction is a force that resists the movement of two contacting surfaces that slide relative to one another..
