PPT-Friction What do you Remember about Friction?

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. 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. . Mr. McMartin. Beta Pod Science. 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.. 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.. 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. 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. 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:. 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?. 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..  . In-Class Activities. :.
