    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:

    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

    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 And Toy Cars

    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

    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

    Research Question How is the coefficient of friction between two surfaces related to the deceleration of an object? Introduction Besides for the fact that friction is a drag (pun intended), humans have utilised this motion opposing force, to its greatest potential. One of the most prevalent things, though generally perceived as overused, the automobile, could be considered the epitome of friction utilization. The principles of friction applies to everything, especially that to that of a car 's

    How Cars Use Friction

    There are two types of friction. They are static friction and kinetic friction. Static friction is the friction you have to overcome to make an object move and kinetic friction is friction that is happening while an object is in motion. An example of static friction is like trying to push a car down the road. It is harder to push from a stop than from a roll. An example of kinetic energy is like your tires on the pavement while you are driving down the road. First, I want to explain how the

    The hypothesis tested in this experiment was, “If the surface material is more roughly textured, than the amount of sliding friction will increase.” This hypothesis was supported by the experiment in all nine trials. In the experiment, it was evident that when a material is rougher, there is more sliding friction. When testing the smoothest material, masonite, it only took an average of 4.6 washers to have to block move significantly across the surface. When testing the in-between material, the cloth

    experiment, frictional resistance, friction is studied. Friction is the force that is parallel to the surface and goes against the force of motion. Friction is dependent on the material of the two surfaces acting upon each other. Two types of friction were observed. Kinetic friction is the friction of two surfaces in motion. Static friction is the friction that must be overcome in order for an object to be in motion. Static friction will always be greater than kinetic friction because it requires more force

    Friction and Dynamics of Rock Avalanches Travelling on Glaciers Rationale The study of rock avalanches travelling on glaciers or glaciated areas has centred around interpreting data collected from case studies throughout history. Looking at this data can confirm that, in general, rock avalanches travelling on glaciers have a reduced coefficient of friction compared to rock on rock avalanches. The decreased resistance contributes to a higher velocity and further distance travelled. The
