An experiment to determine force required to pull a shoe with varying mass

Make sure several inches of the pages overlap. The pages of the books will be woven and the spines will be facing out. So the rice had a firmer hold on the stick. Have someone ready with a timer if you want to make measurements. Have a game of tug of war with the books.

Do some tests with interlacing the pages. You can also try dropping the pieces of papers from a higher spot, like while standing on a table or over a balcony. Does the time difference become more noticeable this way? Then the back page of book A and the back page of book B.

When you grab the chopstick and pull up, what happens? Explaining Friction Fluid friction - friction that happens when an object moves through a liquid or gas.

When you are done with the experiment, just unlace the pages one by one to release the books. Without getting too technical, friction is simply a force that reduces the motion between objects that are in contact with each other. Textbooks work great as well. Do this a few times to compact the rice and get rid of the air pockets.

The wadded piece will fall to the ground immediately. Pull on the books to see if you can pull them apart. Try sticking the chopstick down into the bottle. How do you make the rice stick to the chopstick so you can just pick it up?

What if you only weave every ten pages or every twenty? Floating Paper Air Fricton Two pieces of paper Timer optional Air friction air resistance or drag is a type of fluid friction. What differences do those make?

Hold the pieces of paper above your head. Most people have a hard time understanding friction because the term is used to describe a force that works in a wide variety of ways. You may have to add more rice as well.

Before you begin, just half the books and put them together to show how easily they will come apart that way. This time, when you pull up on the chopstick, you should be able to pick up the whole bottle.

How does it work? Click thumbnail to view full-size Holding up the bottle with just a chopstick! The stick should just come right out. Contact Author What surfaces create the most friction? Now grab one of the book spines and have a friend grab the other spine.

Test which surfaces create more friction, see how strong friction is, learn how to reduce friction, and even discover the side effects of friction.

Ok, What Is Friction Anyway? Sliding friction - friction that occurs when two surfaces slide over each other. Now, interlace the pages by alternating a page from each book. In general, the smoother an object, the less friction it will create.

The books will stick together like glue because each page is exerting friction against the page from the other book.record the force of friction because when I pull the block my pulling force will be measured on the Newton meter, so therefore if the block is moving at a steady speed the force of friction will be the same as my pulling force.

3) Once the block is moving at a steady speed I will record the results. forces & Newton’s laws of motion. physics N 2 forces (examples) a push is a force a pull is a force is defined to be the force required to impart an acceleration of 1 m/s2 to a 1 kg mass there are other units, e.g.

pounds (lb) we could use, ! your bathroom scales measure the force you exert on the scales normal force on scales. To investigate the force required to move a mass along a circular path.

Verify the theoretical Experiment part 2: FORCE VS. MASS (Radius and Velocity Must be Constant) In this experiment, describe the relationship between force and mass in uniform circular motion.

2. Using words and a mathematical expression, describe the relationship. c. The amount of force needed to pull the block. d. The contact area between the block and the surface. 4.

How to Do a Friction Science Experiment

Which statement is consistent with the data collected in Experiment 1 and Experiment 2? a. A greater contact area between block and surface results in greater friction force.

b. In the last video, we had a ten kilogram mass sitting on top of an inclined plane at a 30 degree angle And in order to figure out what would happen to this block we broke down the force of gravity on this block into the components that are parallel to the surface of the plane and perpendicular to the surface of the plane and for a perpendicular component, we got 49 times the square root of 3 N.

Stretching Mass. Students measure the amount of force gravity exerts on objects of different mass by and measure the movement of the car with varying amounts of mass as a given force is applied. A blast of air from an air pump will accelerate the more mass an object has, the more force needed .
