While playing ball, your friend throws the ball out of your reach. Rather than running for the ball, you walk after it. You know that the ball will stop. But do you know why?. 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). What rooms in your house and school seem to produce the worst shocks from static electricity?. What can you do to minimize or eliminate the problem?. This effect occurs only when electric charges shift from their normal neutral position and is transferred from one object to another.. 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. 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?. 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?. 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. 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. 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…...
