Friction

The two graphs of the distance vs. time graph along with the velocity vs. time graph, accurately supports the hypothesis formed at the beginning of this experiment. From the interpretation of the first graph, the chart vaguely shows the changing velocity (acceleration) as well as positive velocity of the objects motion (as seen from the slight curve upwards). However, from another perspective, it might seem as if the diagram is showing a constant, positive velocity as the line is linear with no…

Introduction: Nano tribology is a study field of interfacial phenomenon in nano scale. The interaction between two contacting solids during a relative motion from atomic to microscale is important to understand the friction, wear, adhesion, indentation phenomenon. Now a days it has a plenty application in micro electro mechanical system (MEMS), nano electro mechanical system (NEMS), magnetic storage, lubricant manufacturing and many more field. There are few instruments in the market…

respects to time to calculate the acceleration, spring constant, and damping factor. The experiment was split into two different labs. Part one, the drop test, to take the block to a fixed height and drop it. This would then allow us to calculate the friction force, along with the acceleration of the metal block. Part two, the bounce test, is attaching the metal block to the spring, pushing the block down and releasing it. We would use these data to calculate the damping factor and the spring…

coefficient of kinetic friction, and the tension present in the string. These values will be found by setting up a system in which a cart is placed on track with a negligible amount of friction and attaching it to a weighted hanger with a string. The acceleration of the hanger will then be measured using the Vernier motion detector. The expected results of this lab include: the acceleration due to gravity being ~9.8m/s2, coefficient of kinetic friction being 0 due to the friction-less track, and…

three materials previously used. We observed that among the three materials used, the sand paper has a higher coefficient of friction than the two remaining materials.This is true because sand paper was the roughest material of all the three types of material we used in this specific experiment. We can logically conclude that the rougher the material, the higher the friction it cause, and hence higher coefficient of…

movement of a solid object through a fluid. It’s created by friction forces, that act parallels to the object’s surface. Thus, by transferring the momentum from the arrow to the air, the arrow is stalled. There area unit 2 styles of drag that act on the associate arrow: shear drag because the arrow flies through the air, mechanical energy is spent to maneuver the fluid out of the means, therefore, the arrow could pass. this can lead to friction. The shear drag is proportional to the rate of the…

competitively as well. The Blue Devils are a well known, professional, marching band. Nevertheless there is a lot of physics involved. Whether it’s the tempo of the song, this would involve speed, other things are in factor too like velocity, acceleration, friction, and momentum. Mostly in the movement. To start, the speed refers to the a lot of things. It could be the tempo, for example, 166 beats a min to 100 beats a min or whatever. This affects the speed of the marchers as well. In this…

Goal The goal of this experiment is to verify Newton’s 2nd Law of Motion. Introduction Newton’s 2nd Law states that when an external net force acts on an object, the acceleration of the object is proportional to the net force, and it also occurs in the same direction. The acceleration is also inversely proportional to the net force. Thus, the net force, which is the sum of all the forces acting on an object, is equal to the mass of the object multiplied by its acceleration. In this experiment,…

additional friction may result in the gain or loss of momentum within the system. Our numbers obtained through the experiment and equations, allowed us to conclude that kinetic energy is conserved in elastic equations, but not in total inelastic equations supporting our second hypothesis. However, we noticed that there were still minor amounts of kinetic energy lost during the elastic collisions. This is most likely due to friction, because the track provided does not completely remove the…
