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 which of these actually will affect the coefficient of friction. Friction, which is the friction, which is present when the object is stationary and kinetic friction, this type of friction is present when the object is moving.
1 the problem statement, all variables and given/known data this is a theoretical question from my homework we did a lab in class where we were using motion to see how kinetic friction is affected by different variables we found the acceleration of a sliding wooden block (sliding on another.
Dynamic friction: for the dynamic friction experiment, the force of friction will be read off the force meter this is due to newton’s second law stating that f net = ma when the block is being pulled along at constant speed, the acceleration is 0 so f net = 0. Figure 5 1 wooden block with 2 surfaces covered with rubber in measuring the coefficient of static friction (as), the set-up was prepared the ramp was placed in the table, then the wooden block was placed on the ramp. Using a ramp and a wooden block with two surfaces that were  free assignments determining the static and kinetic friction of wood the coefficient of static friction was determined using the equation as = tang next part was determining the coefficient of static friction, a software device to measure friction that was being. This experiment measures the coefficient of static friction (μs) and kinetic friction (μk) between objects of different materials friction is a force that must be overcome before an object can move across a surface a plain block of wood and a block of wood with sandpaper on one side and glass on the other were used.
For coefficient of static friction, the angle of smaller area for wood to wood was 130 while the angle of larger area was 160 for wood to rubber, the angles for small and large area were 280 and 310 respectively. Friction page 1 lab: friction william morris leo hayes high school friction page 2 purpose: to investigate the coefficient of friction for a given surface and the effects that factors such as weight, surface area and changes to the surface have on the coefficient of friction.
Our goal is in determining coefficient of static and kinetic friction, using the following two equations: sf and k = m2g ã â (m1 + m2) a n fn in a series of trials, the average block normal force is found to be 048(g), with an average external force of 0349(g), yielding an average coefficient of static friction of 0727.
Materials required: a rectangular block of wood with a hook , set of weights, strong thread and a spring balance theory: the force of friction acting on a block of wood is proportional to the normal reaction acting on the block by the third law of motion, normal reaction is equal to the weight of the object. To make sure it is a fair test i will: use the same newton meter and the same wooden block to avoid introducing other variables i will also use the same section of table using the same side of the block every time. 2 the entire process from part 1 was repeated three times and the force of kinetic and static friction for each trial was recorded part 3 1 the experiment then called for the force of kinetic and static friction for the glass surface and sandpapered surface blocks 2 repeat parts 1 – 3 while using two flat surfaces around the house.
Essay writing guide learn the art of brilliant essay writing with help from our teachers what is the effect of mass on friction planning: o a balance o seven 100g weights the experiment will be carried out using the block of wood as the object being pulled across a certain surface to find the coefficient of friction my surfaces will. Transcript of friction experiment attach wooden block to the newton scale and then to car 1 2 weigh the mass of car 1 with the wooden block in kg 3 place car on carpet surface and let it run for 3 meters 4 measure the velocity of car 1 with the wooden block on the tile surface 5 find the force of friction by using the f-net equation. We did a lab in class where we were using motion to see how kinetic friction is affected by different 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.
