Experiment 5 ~ Friction Purpose: In this lab, you will make some basic measurements of friction. First you will measure the coefficients of static friction between several combinations of surfaces using a heavy block and a set of hanging masses. Next, you will measure the coefficient of kinetic friction between two
The rubbing produces friction and the result is heat. When oil is added to a car engine, the oil sticks to surfaces, and helps to decrease the amount of friction and wear on the parts of the engine. An engine that runs hotter requires a more viscous oil in order for it to stick to the surfaces properly. Measuring Friction

A block with an initial speed of 1 meter per second slides 5.8 meters down a ramp inclined at 72 degrees in 1.1 seconds. What is the coefficient of friction between the block and the ramp, rounded to the nearest hundredth? Answers. The following are the answers to the practice questions:
Putting this value of a in the second equation the contact force between the two blocks come out to be R= (m2/m1+m2)×F. Now, I suggest you to do the same exercise considering that the force F is acting on m2.

Dry friction, also called Coulomb friction, occurs when unlubricated surfaces of two solids are in contact and slide or tend to slide from each other. If lubricant separates these two surfaces, the friction created is called lubricated friction. This section will deal only with dry friction. P W N f R Ø
physics. 1 kgand 4 kgblocks lie on a rough horizontal surface. The coefficient of friction between 4 kgblock and surface is 0.2while the coefficient of friction between 1 kgblock and the surface is 0.6. All the pulley shown in the figure are massless and frictionless and all strings are massless. A.
