Static and Kinetic Friction Essays

* Duncan, Vinny, and Wayne are all friends working - or wasting time - the summer before senior year in high school. Duncan is the soul, Vinny the brains, and Wayne the muscle. At the end of the previous summer, Duncan tried to save a drowning girl and failed. Not being a hero has really affected his life, particularly his relationship with his girlfriend Kim. Also, he is now terrified of swimming, especially when the nightmares come back. Duncan's summer job is with the public transit lost and found. While trying to make the hours go faster, Duncan looks through the items, especially the books and golf clubs. One day he discovers an unmarked journal with no name, which depicts sadistic animal torture

The book, Acceleration, by Graham McNamee, is about a boy named Duncan, who works at the city’s Lost and Found, discovers a leather diary that belongs to a serial killer that Duncan nicknamed Roach, who is on the loose. Duncan finds out that Roach is targeting humans, specifically women, and tries to find the killer and stop him before it is too late. The main topic of this story is that mystery can make us do the unexpected. Once, the killer writes, “This is kids’ stuff… Need something BIGGER” (Mcnamee 47). Also, when Duncan was searching up books about murders, a certain passage from a book caught his eye, “Mason Lucas has a name for this ‘escalation of increasingly destructive aberrant behavior’... He calls it acceleration”(Mcnamee 88).

Something that can be learned from this data is that the sandpaper had the the most time. Therefore, it had the most friction. The material’s surface affected the speed it had. The aluminum foil had a very slippery surface. The aluminum foil went down the fastest on the ramp. Differently, the sandpaper went down the ramp slowly. The material’s surface affected the amount of friction. The sandpaper had the most friction because of its rough surface. Aluminum foil had the least friction because it had a smooth surface. To sum it up, the material’s surface has an effect on the amount of kinetic

The objective of this lab was to explore the behavior of centripetal acceleration and identify the relationships between the acceleration and several forces acting on the object.

The two types of friction of the mousetrap car are rolling friction and static friction are the two types of friction that may affect the performance of the mousetrap car. The problem of the friction did I encounter and how do you solve them one types of friction i encounter was the static friction I had to take off some glue from the stick that had my wheels and to open eye screws. The factor did take into account to decide the number of wheels you decide to chose for the mousetrap car I saw a video of a car that had 4 wheels and it ran really fast, so I thought a 4 wheeled car would run fast or at least the four meters. What kind of wheels did I use in each axles I use tires as my wheels on each axles. I think the affects on using big wheels

In conclusion the relationship between the properties of skin and friction skin impressions is that without these characteristics or capabilities fingerprints wouldn’t exist. The

I will start with the beginning, which is the ramp and marble. We used a marble that had more mass than the others. We did this to give the marble more potential energy. We set the marble at the top of the ramp, which gave it more potential energy as well, and released the marble. Once dropping it, it's previous potential energy transferred into kenetic energy. After this step came the metal lid. What this step showed was rolling friction and it also pushed it forward. How exactly? Well, when the marble landed, it bounced up, giving it elastic-type energy. It then fell, making it roll across the top of the lid the rest of the

Graham McNamee’s Edgar Award winning novel, Acceleration, teaches us the importance of finding closure in guilt, allowing us to find redemption in guilt when as well as to be nevermore distressed by guilt. However, the importance of finding redemption in our guilt is further evident than just this novel.

2. Yes, my right hand does experience a force. When I pull with my left hand I do add force with my

For experiment one you will be testing road surface, and seeing if it will affect the speed of the hot wheel car. Before you begin your experiment, you will need to set up your tracks. Tape the two yellow tracks together,line them up and tape the front and back. Then take the top of the track and tape it to the left side of the desk in the back of the room, be sure to tape it 72 cm high. Once you tape the top, tape the bottom of the track 97 cm away from the base of the desk. Step four is to get 40 cm of the material you are testing, the floor, sandpaper, and wax paper. Use a stopwatch to conduct three trials for each surface material, from the top of the track to the end of the surface material. Finally, record the results in a data table

Friction is an opposing force. It acts in the opposite direction of the marble or the roller coaster cart. When designing a roller coaster you want to have as little friction as possible. This goes the same way with my model track, i want to make sure the track is designed to where friction will not be a worry factor but i want there to be enough of it to keep the marble from going to fast and running off the track. The force of gravity will help take some of the pressure off the importance of friction but with the marble being so light i am more than likely going to apply more friction only because the weight of the marble is so light. If the laws are correct i should have a successful marble

Newton’s Third Law of Motion (every action has an equal and opposite reaction) mainly concerns friction, which is the energy or resistance resulting from two surfaces coming into contact with each other. Without friction, cars would not even be able to move properly without sliding around

Friction is the force that opposes the force applied on an object, as well as the motion of the object. The two types of friction covered in this lab are kinetic and static, but there are other types as well. Static friction ƒs opposes motion so that things do not move in relation to each other. Kinetic friction ƒk is the friction when objects are already moving in relation to each other. Examples of static friction and kinetic friction are riding a bike and moving furniture across the floor, respectively. It is important to note that friction is not dependent on the size of the area of contact between two surfaces assuming uniform surfaces. It is known that as the block pushes on the table, the table pushes back. This force is known as the normal force (ƒN) which is the equal force perpendicular to the object. In this experiment, it is noted that the table and room are stationary objects, and thus have no acceleration on them. This means that when the block is also stationary, the net force on the block is zero.

When two objects get in contact with each other the force between them forms. Scientists call this force the frictional 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.
