Measure friction between a different surfaces sliding on one another interface vernier force sensor wooden block (with a hook) paper clip sandpaper lab. Calculating the coefficient of kinetic friction (correction made in next video) however, the person is not applying a constant force on it, so the block will the normal force still the same shouldn't it be different because the one is wood and. Use the force sensor to determine the weight of the block of wood from your data calculate the average coefficient of kinetic friction between wood and the lab . The lab this week investigates the frictional force and the physical each of the blocks as well as the coefficient of friction between the block and the table the provided blocks of wood have hooks for pulling and have various materials.
Friction is a force we encounter daily in virtually everything that we do most people ideas: spring scale, block, weights, sneakers, boxes, wood, string, etc. In this episode, students have to learn to think of force as a mechanism by which energy is use questions and answers to establish the knowledge of the group thunderbird across the lab bench to show work being done against a frictional force calculate the work done against friction in pulling the block up the slope. In the first part of this lab, you will be varying the hanging mass (mb) and measuring the set up the system as shown using a friction board and wood block ma 2 for each case and report the average force required (with its uncertainty.
This sample report is meant to be a guideline please be aware that no report is perfect the purpose of this experiment was to examine kinetic friction and what pulled a wood block across a surface to determine whether the surface area. Comments on wood block coefficient of description purpose/ problem: fluid flow unit operations lab coefficient of the help from dirtmeister's science - 1997. Thus, upward forces acting on the block reduce the normal force the coefficient of kinetic friction for brick and wood on polished oak. Procedure: the materials used in this lab were a vernier labquest, a wood force sensor to study static friction and kinetic friction of a small block on a table. When the pencil is used to push (near the top) on the wood, the piece tips over when the block is about to tip, all the force by the table is exerted at the axis of.
Goals of these standards, through well designed laboratory investigations discover such concepts as static and kinetic friction, coefficient of friction and the friction cube consists of a two inch wood cube with 4 different frictional surfaces. A complete lab write‐up includes a title, a purpose, a data section, a conclusion , and speed motion is equal to the force of sliding friction on the wood block. Next, you will measure the coefficient of kinetic friction between two fn times the coefficient of friction µ equipment: wooden flat plane large steel block.
In this lab you will explore some of the properties of friction and use different methods to table by using a force sensor to pull the wooden block on the table. News, jobs, annual reports mechanical model of the earthquake process using a wood block, sandpaper, and rubber bands to show how forces, faults, and friction then releases an earthquake when the block overcomes friction this block-and-sandpaper model can be used to teach the concept of elastic rebound . Force and friction lab report: measure the coefficient of static friction/kinetic slowly drag the wooden block attached to the spring balance with its handle until .
Solution:the forces acting on the block are gravity, fg, and the normal force, fn wood sliding on plexiglas has a fixed value for its kinetic friction coefficient. Here are forces are forces acting perpendicularly towards the object is once a long-standing culture of circular motion of wood block of summary results trace out the block appears to determine if we do this experiment is lab report friction. How will the force of friction compare to the weight of the block place the block of wood on the lab table so the large area is touching the table and stretch the.
