1 Name: Block: Date: IP 670 All About Friction Introduction: The force of friction is one of the hidden forces that affects the motion of objects. Forces like these are hidden in the sense that they are so common that we sometimes take them for granted and overlook them. The force of friction and other hidden forces must be recognized if we are to describe and predict motion accurately. 1. Symbol Term Unit Name Unit Symbol F Force 2. Friction is the that the. Demonstration One of your teachers (or a volunteer) is going to push a book across the table. 3. PREDICT what is going to happen to the motion of the book when the person stops pushing it. (CIRCLE YOUR CHOICE) a. The book will keep moving at the same speed as when the person was pushing it b. The book will speed up after the person stops pushing it. c. The book will slow down after the person stops pushing it. 4. What did you OBSERVE happen to the book? (CIRCLE YOUR CHOICE) a. The book kept moving at the same speed as when the person was pushing it. b. The book sped up after the person stopped pushing it. c. The book slowed down after the person stopped pushing it. Standard(s): 1.5, 1.6 TA: Independence Level: % Assistance, coaching, prompting:

2 5. EXPLAIN Why do you think the book moved the way it did after the person stopped pushing it? Drawing forces: 6. If the book is pulled at a slow, constant speed, the forces on the book are: (circle the correct answer) a. balanced. b. unbalanced. 7. Arrows are often used to show forces. The diagram below shows a book being pulled to the right at a slow, constant speed. Draw and label a second arrow to show the force of friction that acts on the book (make sure it points in the correct direction and is the correct size). F pull 8. Friction points in the direction as the pulling force. a. same b. opposite 9. The friction force is size as the pulling force. a. the same b. not the same

3 Measuring Friction: 10. If the book is pulled at a slow constant speed, the pulling force should be the same size as the friction force. The teacher (or a volunteer) will pull the book at a slow, constant speed across the table with a spring scale. The force that is read off the spring scale is the same size as the force of friction. Force of friction on the book = F friction = N Does friction depend on the TYPE OF SURFACE? 11. Your teacher will show you two different surfaces. a. Predict: Which surface will have more friction? (Your teacher will test this by dragging a wooden block across it.) b. Explain: Why do you think this surface will have more friction? c. Observe: Your teacher (or a volunteer) will drag a wooden block across the surfaces using a spring scale. Which surface had more friction?

4 12. DESCRIBE: Surfaces with a lot of friction are... Surfaces which don t have much friction are... Does weight affect friction? 13. Harry is working for High Velocity Movers when he comes upon two boxes that look identical, but one is filled with feathers and the other is filled with books. Instead of picking up the boxes, Harry pushes each one along the ground. Which box is going to have a larger frictional force acting on it? a. The box filled with feathers (weighs less) encounters more friction. b. The box filled with books (weighs more) encounters more friction. c. Both boxes experience the same amount of friction.

5 14. The class needs to come up with an experiment to determine whether or not weight affects the force of friction. Describe the experiment in the space below: 15. RECORD any data taken in the space below: 16. Write one or two sentences that describe the relationship between weight and friction.

6 Static & Kinetic Friction: 17. Your teacher (or a volunteer) is going to try to push an object, but it won t move. What force is opposing the person s push and preventing the object from moving? 18. Your teacher (or a volunteer) is going to push the same object again, but this time it moves. Is there a force opposing the person s push now? a. Yes, there is a force opposing the motion. b. No, there is not a force opposing the motion. If there is a force opposing the motion, what is the name of the force? 19. Most people think of friction as a force that affects moving objects. Friction can affect both moving and non-moving objects: Static Friction Kinetic Friction Examples: Friction that acts when two surfaces ARE NOT moving past each other. Forces which act between surfaces Friction that acts when two surfaces ARE moving past each other. Examples:

7 Air Resistance? 20. Predict: Your teacher (or a volunteer) is going to drop two pieces of paper: one piece of paper is flat and the other is crumpled up. Which piece of paper is going to hit the ground first? a. The flat piece of paper will hit the ground first. b. The crumpled up piece of paper will hit the ground first. c. Both pieces of paper will hit the ground at the same time. 21. Observe: What did you observe when the pieces of paper were dropped? 22. Explain: Which factors affected how the pieces of paper fell?
