Experiment - friction

Friction is a force that resists motion. It involves objects in contact with each other, and it can be useful or harmful. Friction helps when you want to slow or stop a bicycle, but it is harmful when it causes wear on the parts of a machine. In this activity, you will study the effects of surface smoothness and the nature of materials in contact on sliding friction.

Friction 2018-09-26 · Work with a group to investigate friction and to see what happens to the distance a toy car travels when you change the surface at the bottom of a ramp. This project utilizes the Microsoft Excel Software to display the graphical representation of (profile) that shows the relationship between the ratio of belt tension and the lap angle. This work (experiment) was carried out in the mechanics Discussion The aim of the investigation was to determine the friction coefficient of different materials on an inclined steel plane. The main causes for opposing force of friction are molecular adhesion and surface type and the objective was to discover difference sin surface type of each of these materials: whether any existed, and if so the value of difference of each. Head out to your nearest slide and explore gravity and friction! This playground science activity is a great way for young children to explore physics using a variety of materials right in their own backyard or at the neighborhood or school playground!

Selection of friction boards or materials; Forcemeter (0-15N if masses are added) A selection of different materials may be put out with this equipment for pupils to use in groups. Because the material needs to be fairly taut, it may be easier to make up some friction boards that can be reused many times. 2017-12-19 An investigation into friction, told through the animated story of Rapunzel. The investigation covers the importance of prediction, fair testing and repeating any measurements taken.

Friction burns often happen Understand that friction is a force resisting motion.

The force of friction acts against the direction of motion.Note that F k < F s and consequently, μ k < μ s .. If the externally applied force (F) is just equal to the force of static friction, F s, then the object is on the verge of slipping, and the coefficient of friction involved is called the coefficient of static friction, μ s.

An experiment may include multiple experimental groups at one time. A control group is a group separated from the rest of the experiment such that the independent variable being tested cannot influence the results. While all experiments have an experimental group, not all experiments require a control group.

Students will construct a simple, balloon powered car at home. They will "race" their cars on three different surfaces: carpet, linoleum, and concrete.

elastoscale … a Draw a diagram of your experimental apparatus. This type of practical apparatus may help your investigation In a series of three experiments we have a look at how friction can be looked at and determined.

E) A control group assures that an experiment will be repeatable. If the experiments are difficult on the first week of the electrostatics lab, they will be left up so you can try some of them with the Van de Graaff experiments in the following lab. When the air is humid, a thin, invisible film of water forms on all surfaces, particularly on the surfaces of the insulators in the experiment.

The low friction thing happens to cars when it rains. That's why there are often so many accidents. Even though the friction of the brakes is still there, the brakes may be wet, and the wheels are not in as much contact with the ground. Cars hydroplane when they go too fast on puddles of water.
