PPT-The Force of Friction Friction opposes motion between two surfaces that touch each other.

The amount of friction depends on Surface Roughness Forces pushing the two surfaces together Types of Friction httpsappdiscoveryeducationcomplayerviewassetGuid72E28A590EAB4EC9A097365513460023. 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 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. . October 29, 2014. Chapter 10 Forces. Force and Net Force. Force is a push or a pull on an object.. Net force is the total force on an object.. Unbalanced Force. Balanced Force. Unbalanced Force. . can cause an object to move, stop moving, or change direction.. 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. . Pull Force. Reaction . Normal Force. Friction. Coefficient of friction = Pull Force/ Normal Force (weight). Surface. Brick. Free Body Diagram . Since block remains on same horizontal plane, it gains no potential energy.. 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.. 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..  . Forces. Forces. Forces have . Magnitude . and . Direction. . We represent these in diagrams with arrows. . Larger the force the bigger the arrow. . 50N in Each direction. Forces and Motion. When we look at a diagram we can figure out the sum of forces. . 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:. Surface texture. Surface material. Surface area. Speed of slide. Mass. Weight. Angle of surface. Normal Force. What is the mathematical relationship between…... How do balanced and unbalanced forces affect an object's motion? . Inertia. is the resistance of any physical object to any change in its state of motion, including changes to its speed and direction. . 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. friction. What do you Remember about Friction?. 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..
