Friction

resistance, or friction. It occurs because of the imperfections in the surfaces of objects, the molecules of both surfaces interfere with each other creating a natural force between two objects. The friction opposes direction of motion of the object and is parallel to the surface on which the action takes place. The force and magnitude that are necessary to overcome friction can be calculated. Area of objects that is involved in the contact is disregarded when calculating friction. Objectives:

Friction is the resistance to motion of one object moving relative to another and it is created when two surfaces move or attempt to move across each other. Friction is a non-conservative force, which is defined as a force that does not store energy. The fact that friction is a non-conservative force means that the kinetic energy involved in friction is transferred into thermal energy (heat). One of the method is using a spring balance which was used in the actual lab and is done by pulling a

This lab was a about surface area and friction. How an object could be pulled along different surface areas and then their might be different outcomes. The labs will also explain surface area with frictional force. Some surfaces could be much rougher than others. Bar graphs were also made to compare the differences between the different forces. Scales were used to see how much force in newtons it would take for the block to be moved across the surface. The surfaces that were being tested were tabletop

The two different types of friction that affected the performance of our vehicle was the concrete floor and the elastic band winded around the axel. We first used the elastic band connected with string but we changed it after not the first test. The problems that we had with the friction was that it kept on stopping our vehicle. The concrete floor had some bits and pieces in the way and was a little bumpy in the area we tested (not the real test). We solved this friction problem by clearing the concrete

Friction Lab Formal Report Tayado Langley 12/10/14 Period 1 Abstract This experiment was created in order to enhance our understanding about the causes of friction. This was achieved by testing the friction on various surfaces. The first thing I did was gather the materials ( a bottle , some blocks of wood , string and surface materials.) Then I attached the string to the block of wood and the bottle. We then began to add water in the bottle until it began to move. Our results

The force of friction can be increase by choosing having a rougher surface to pull the object across. The surface used in this lab was a table so it was very smooth and the objects glided when pulled. A rougher surface like sand or dirt would increase the amount of friction produced. Friction, static or dynamic is the normal force between the surfaces multiplied by the coefficient of friction. But another way to think of it is that friction is a function of the pressure between the two surfaces (force

Experiment 37: Friction Jalicia Ruttino Jr482715@ohio.edu Cole Raisbeck 10/04/2017 Abstract: The main objective of this lab was to measure the friction force it takes to start moving a weighted block across a table, and as it continued to move. This force was tested experimentally in three separate ways. The force was then solved graphically and mathematically through six different runs per method. TALK ABOUT RESULTS HERE. Theory: Friction is the force that opposes the force applied on

Friction is a force that two surfaces exert on each other when they rub together. This experiment tested the effect of wood, sandpaper, and carpet’s frictional force on the distance traveled by toy pull-back cars. The hypothesis was that the toy cars would travel the furthest on the wood, because its smooth surface would create less friction, causing less of the car’s energy to be absorbed by frictional force, and more of the car’s energy to go towards speed and distance. The results proved that

wheels on a car the friction will slow the car down and make it go slower. The car with the most wheels traveled at an average of 79 cm and that was the worst out of all of the cars tested, the car with the most average wheels traveled the farthest in the experiment. The science behind friction is friction is a resistance between surfaces sliding together. Basically friction converts kinetic energy into heat and if the surface is rough the friction will increase. Without friction life would be like

experiments revolves around the force and coefficients of friction. Static friction is the force that prevents a stationary object from moving. The direction of static friction is opposite to applied force. Kinetic friction is the force that acts against an object’s motion. The direction of kinetic friction is opposite to the object’s velocity. Frictional forces act parallel to the surfaces they act upon. The coefficient of kinetic and static friction both show the magnitude. Between the forces and the
