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 primarily caused by the chemical bonding of molecules at the surfaces of objects in contact (intermolecular forces which are electrical in nature). Friction. By: . Mashael. Saud . Alharbi. *If we examine the surface of any object, we observe that it is irregular.. *Such surfaces that appear smooth to the eye, show irregularities.. * Under microscopic examination ,. Friction: A Force that Opposes Motion. The Source of Friction. Friction – a force that opposes motion between 2 surfaces that are touching.. Friction occurs because the surface of any object is rough. If surfaces that look or feel smooth have microscopic hill and valleys that can stick to another surface. . Give me another instance when on its own an object stopped moving.. Carrom. coins. Activity of two students to show opposing forces.. An opposing force always opposes ___________. In a rolling object motion is opposed therefore . 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.. 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.. Friction. Friction is the resistance force when 2 rigid solids slide (or attempt to slide) across one another. FYI: Drag is a resistive force when solid fluid flows through a liquid or a gas and has different characteristics. 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.. 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. produced by different activities. Stay safe. . Whether you are a scientist researching a new medicine or an engineer solving climate change, safety always comes first. An adult must always be around and supervising when doing this activity. You are responsible for:.
