Friction

uncertanties accountered in the accelerated motion lab. Firstly, the presence of air resistance. As the object traveled down the ramp increasing its velocity, air resistance increased which affected the acceleration. Secondly, the affect of friction. The presence of friction affected the motion of the object as it went down the ramp. Lastly, the imperfections of the ramp. The wear of the ramp could have caused the object to reduce its rate of acceleration. Conclusions…

heavy to move in its current state. The friction between the rug and the desk was high. Also, when I tried to pull one of the sides, the legs in the other side of the desk gave a squealing noise, which made me afraid I would break it. I realized I had to solve these two problems in order to move the desk: move both legs at the same time and reduce the friction. My solution: find a cardboard long enough to place underneath the desk. This reduced the friction and allowed me to move the desk…

therefore unbalanced forces are acting upon him. Bennett is the object and his mass compared to the block’s mass causes his acceleration to happen when he pushes off the block and into the air. There is also a friction force when he is positioning his feet on the block to move his feet kinetic friction is in action. In newtons 3rd law “ for every action their is an unequal and opposite reaction” Their isn't an action when Bennet is at rest with his two feet still on the block. However when he…

The carpet can create large amounts of friction and the incline of the test course would cancel it out so that both the component of the gravitational force pushing the ball down the slope and the frictional force opposing it would be balanced leading to constant motion. As per Newton’s first Law of Motion, the Ping-Pong ball should maintain a constant velocity under these conditions. The rough corrugated sheet would produce too much friction and slow the object down as the frictional force…

In this experiment, the objectives were to derive an equation for the tension in the string (which had a mass attached and was revolved in a vertical circle motion). In order to complete this, the velocity of the mass would have to be calculated using the measured tension, and this value would then be compared to the expected velocity. The second objective of this experiment was to observe how mass, velocity, and radius affect the tension of the string. These objectives were reached in this…

At (a), the surface is not inclined. When a vehicle moves around a bend or a corner on a flat road, it is moving in circular path. Therefore, it will experience centripetal acceleration and there must be an external force causing centripetal acceleration. As shown in the diagram, the only thing in contact with the car is the road, which is between the tyres of the vehicle and the surface of the road. Therefore, we can know that the frictional force exerted between the tyres and the road directed…

Protection (Caleb) Laws of motions Fimpact=maaverage=m ∆v/∆t The above equation is rather important. In below, we will talk about the safety measurement in modern cars, and the theory behind of them can be explained by this equation. This equation is derived from Newton second law F=ma, and the acceleration also can be derived to be change in velocity divided by change in time. When collision occurs, the impulse(Fimpactt) is constant, hence the only factor we can change is the time impact time…

Friction loss is defined as the pressure loss or head loss that usually occurs in pipeline fluid flow because of the viscosity effect near the surface of the pipe. When the fluid flows along the pipeline, it produces frictional resistance thus results in loss of energy or total head loss of the fluid. Therefore, experiment was conducted to verify the Darcy Weisbach equation by determining the pressure loss along a horizontal pipe. Figure A below shows the diagram of friction loss along a…

Figure (4.2): Failure pattern of cylinder specimen (CY1). Under pure axial compression loading for cube specimen (C1), the failure cracks generated are approximately parallel to the direction of load as shown in figure (4.3) with some cracks formed at an angle to the applied load. As a result, lateral shearing stress is produced in the cube specimen. The effect of this shear decrease towards the center of cubes; so these sides of the cube have near vertical cracks at the cube center.…

Physics is everywhere. Especially in NASCAR which stands for National Association for Stock Car Auto Racing is a racing sport which the racing cars have motion. “NASCAR is motorsport's preeminent stock-car racing organization. The three largest racing-series sanctioned by this company are the Sprint Cup Series, the Xfinity Series, and the Camping World Truck Series.”(Mukul Bhatia.What is NASCAR?.www.quora.com.) On the rough racetrack nascar cars are made to be driven in extreme conditions. In…
