Galileo based his concept of friction on these experiments. Sir Isaac Newton (1642-1727) was born by the year Galileo died. In his first 24 years he had already formulated his first three laws of motion.

Friction is the resistance that one surface or object encounters when moving over another according to a dictionary definition I read. As a part of the the A-Z Science Experiments for Kids series hosted by Frogs and Snails and Puppy Dog Tails, my son and I conducted a series of cool experiments that explored friction. We used items we found around the house to create four different roadways for one of my son’s toy cars to travel on. This simple Science Experiment Exploring Friction. This one was pretty easy and a great way for the older kids to get a “feel” for friction. As the ball slides you can feel it slip when covered in paint. All you need is: A box or a tray with sides; Paper; Paint; Bouncy balls or marbles.

Jan 12, 2017 - Learn how to experiment with friction! Check out this easy friction science experiment that packs a big punch! Kids love this friction activity!

For this experiment, each child chose a matchbox car. I made a ramp out of foam core and poster board, leaning one against a small stool for an angle. We wanted to measure whether friction increased or decreased with different surfaces, so I placed various materials on the bottom of the ramp during each round of racing.

By measuring the pressure drop and flow rate through a pipe, an estimate of the coefficient of friction (friction factor) will be obtained. Two different flow situations will be studied, laminar flow and turbulent flow. View Fluid Mechanics Pipe-Flow experiments.docx from Engineering 48641 at University of Technology Sydney.

Nikuradse (1933; Prandtl 1933), experimenting with pipes roughened internally by a uniform layer of sand, found that such pipes were indistinguishable from perfectly smooth ones, provided that the pressure gradient was less than that given by pV * k/μ = 4, where V = √(T 0 /p), T 0 = shear stress at wall, p = density of fluid, μ, —- viscosity of fluid, k = diameter of roughness grains.

As introduced in the last section, during the process, the precursor material is converted into wire or rod without melting. It is a friction based process and the friction induces heat generation.
