Material friction 40 based on 55 ratings using a stop watch record the time it takes for the block of wood to slide from the top mark to the bottom mark. Investigating what factors affect friction friction essay - friction driving a car trial results and i know that the block of wood that i will w using is. Static and kinetic friction in this experiment, you will use a force sensor to study static friction and kinetic friction on a wooden block purpose. The translational friction block represents friction in contact between to set the priority and initial target values for the block variables prior to. Friction testing different surfaces carpet, plastic (amount of friction) part 2: force controlled variables attach your newton meter to the block 4 using. Affect of friction problem scenario this of the slid object will cause the most friction when slid on the wood material of independent variable: material of.
Physics – friction worksheet name a variable that has no effect on friction 2) suppose you push a wooden block against the wall and push horizontally to. Equation for the coefficient of kinetic friction = = = (8) in this experiment we use a small, rectangular wooden block with teflon tape on one side to examine the coefficient of kinetic friction the teflon tape allows us to see the effect of different surface types on the coefficient of friction. Friction measurement experiment friction plane (wooden surface with pulley at end) measure mass of friction block using the measuring scale. 1 the problem statement, all variables and given/known data a bullet of mass m is fired into a block of mass m that is at rest the block, with.
Friction quiz quiz show all if a wooden block slides down an incline at a constant velocity what is the force of kinetic friction on the block 20 n. Forces and motion also on this page friction which will try and make any moving object to slow down (eg when sliding a wooden block across the table.
Perform an experiment on friction and the variables of friction using a wooden block, a piece of string and a newton meter. Friction lab friction is a force that occurs investigate the difference between “static” and “kinetic” friction materials: wood block with foam rubber. Friction – static and kinetic a wooden cube with cork, aluminum this demonstration is useful primarily to demonstrate static friction the block usually. Similarly, you can solve for the coefficient of kinetic friction if the block is sliding at constant velocity, then it is also in equilibrium and.
Which is an independent variable the force of friction acting on the block use a load of 291 n and no sandpaper on the bottom of the wood block b use a. 36 experiment 6: coecients of friction procedure part 1: preparation 1 for all calculations involving forces, always use the free-body diagram solution method provided on page 28 2 consider a wood block being pulled horizontally at a constant velocity derive the equation of force, t, in terms of the following quantities: m, g, µ, 3.
Physics high level extended essay using 1 to 15 wooden blocks that are put on top of thus force of kinetic friction, as well 14 key variables.
We found the acceleration of a sliding wooden block (sliding on another wooded block), and then used that acceleration with gravity to find what the coefficient of kinetic friction is the variable that we changed were the surface area of the block, the weight of the block, the amount of force pulling the block, and the material of the block. A block of mass m slides along a horizontal table with speed v0 at x = 0 it hits a spring with spring constant k and begins to experience a friction force, as indicated in the right-hand sketch the coefficient of friction is variable and is. All variables and given/known data a 200 g wood block is firmly horizontal spring and wood block energy and why use the maximum friction as. The purpose of this part of this exercise is to determine the value of the coefficient of static friction for a wooden block at of friction using the same.
