Friction

Discussion From this experiment, it can be determined that the value of the coefficient of friction between the wire and the belt is 0.2782 (which is dimensionless). In addition, T1 becomes smaller (so the belt tension ratio becomes greater) when the angle of contact is increased, which can be explained by considering equation 2, as T2 cannot change for a given stationary mass. Comparing the experimental results to the theoretical predictions (made from the calculated value of μ, there is a…

Without directly contacting with them, normal people are hard to truly understand the feeling of the unfortunates. From Huck’s, “Realistic fiction can also illuminate experiences that children have not had” (Huck, p.203), contemporary realistic friction can reduce the estrangement between them.…

uses magnets inside the track, which react with magnets in the car, creating a substantial force against the momentum of the car, causing it to slow to a stop. This was much safer and more reliable than the older friction brakes. Friction brakes used downforce of an object to create friction that would eventually slow the car to a stop. Another safety feature incorporated into modern day roller coasters is the lap bar. The lap bar is used to ensure that riders have less of a chance of falling…

In Falling through Earth might be a long and fruitless trip Air resistance and friction would prevent reaching the other side by Emily Conover, the article starts off by suggesting to imagine what it would be like falling down through Earth’s center by an imaginary tunnel. As the traveler falls, the action would be propelled by the force of gravity and friction, however, air resistance and friction would make the fall of an estimated 12,000 Kilometers slower. A study calculated how factors could…

on figure skating. The three elements I chose to focus in on are friction, momentum, and Newton’s third law. Friction plays a vital role in figure skating. “The biggest difference between dancing on a floor and skating on ice is the lack of friction”(Moskowitz, “The Physics of Figure Skating”). Ice provides less resistance against objects especially the skates. In addition to the less resistance, there is also a low level of friction. This…

to slow it down at the end of the track. But it does come to how the friction from the actual cart and the track would work because in reality you could add brakes and other things to help when it comes to the end of the track. And we were demonstrating our track with small objects that barley had that much mass to create a lot of friction because we only had a small marble, tape, and foam and those don’t create that much friction.…

Sullivan Jackson Kachigan Physics 16 February, 2018 SAHC: SJ How Mass Effects Luge Luge is an unusual sport where the rider or riders on a sled-like device are barreling down an ice track at speeds up to 97 mph. Because of these tremendous speeds, one may think that the rider(s) must be light and nimble so they could glide through the course with ease. However, this is the complete opposite of reality and in the physics world, it makes complete sense. As you may have guessed, the…

Physics plays an important role in the mechanics of a roller coaster. The thrilling ride cannot be appreciated, if the physics of a roller coaster is not understood. The loops, bends and hills are all affected by physics. The first hill of a roller coaster is the initial start of energy. Potential energy begins the transfer of energy on the first hill. A chain motor pulls the cars to the top of the hill creating potential energy. Potential energy being defined as the energy determined by its…

First, we assumed that the there was no friction acting on the cart and that the pulley wheel was also frictionless and spun frictionlessly. This error was systematic and was present in all trials. Friction on the track and string could have slown the cart adding more force to the tension making the cart seem heavier than it actually is in the calculations. A second error…

the inter-fin spacing ratio (Sy/D) 1.944 and 3.417 for Staggered arrangement and Inline arrangement of fins. Nusselt number and Reynolds number are considered as performance parameters. Correlation equations are developed for the heat transfer and friction factor. Computational Fluid Dynamics analysis is done by using…
