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?. 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. 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?. A chair will be placed in the middle of the floor. Teacher question: Are there any forces acting on this chair? . Invite . a student to gently push the chair a short distance across the floor. Ask the same teacher question . 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.. What causes an object to start moving, stop moving, or change direction?. UNBANLANCED FORCE. What is a force?. A push or pull. A force is described by strength and direction. The strength of a force is measured in the Newton (N). Student notes are shown in blue.. Force Defined. Any influence that can cause a change in an object’s motion.. A bat strikes the ball with a force that causes the ball to stop and then move in the opposite direction.. 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.
