Mew is **a small, pink, Psychic-type Mythical Pokémon**. It was added to Pokémon Red and Blue by its creator, Game Freak programmer Shigeki Morimoto, as an intended obtainable Pokemon.

**No , we cannot have zero friction surfaces** . Even if we use a lot of lubricants , the friction will be reduced but can never be reduced to zero because every surface will still have minor irregularities in them.

**Kinetic Friction Formula**

- Kinetic Friction Formula Questions:
- Answer: On a flat surface, the normal force on an object is η = mg. Using this, the formula can be used to find the force of friction:
- F
_{k}= μ_{k}η - Answer: On a flat surface, the normal force on an object is η = mg.
- F
_{k}= μ_{k}η

Static friction is **a force that keeps an object at rest**. Static friction definition can be written as: The friction experienced when individuals try to move a stationary object on a surface, without actually triggering any relative motion between the body and the surface which it is on.

To find static friction, it equals the product of normal force (Fn) and static friction coefficient (Fs). **F=Fn x Fs**. Fs is usually given in questions, and the normal force (Fn) is usually what students need to look for.

mu naught value : µ_{0} = **4pi × 10 ^{-}^{7} H/m**.

**Occasionally, it is maintained that μ is always less than 1, but this is not true**. While in most relevant applications, μ < 1, a value above 1 merely implies that the force required to slide an object along the surface is greater than the normal force of the surface on the object.

**How to find force of friction**

- Choose the normal force acting between the object and the ground. Let's assume a normal force of 250 N .
- Determine the friction coefficient.
- Multiply these values by each other: (250 N) * 0.13 = 32.5 N .
- You just found the force of friction!

angular frequency

**Force of Friction** (Ff) Force that opposes the motion of an object.

Mu has quite a few uses, it is used: As a prefix for measurements to represent ( 1⋅10−6 ) Represent the **coefficient of friction**. To represent reduced mass in a two-body problem. To represent mass per unit length in strings and other objects that appear one-dimensional.

The value of μ0 was chosen such that the rmks unit of current is equal in size to the ampere in the emu system: μ0 was defined to be **4π × 10−7 H/m**.

The coefficient of friction (fr) is a number that is the ratio of the resistive force of friction (Fr) divided by the normal or perpendicular force (N) pushing the objects together. It is represented by the equation: **fr = Fr/N**.

**Fk is kinetic friction coefficient**. It is different from Fs and do not get confused. Generally Fs is greater than Fk for the SAME object and that is why static friction is usually greater than kinetic friction of the SAME object.

The friction force can be determined using an understanding of net force as **the vector sum of all the forces**. So 3.81 N, right = 9.13 N, right + F_{frict}. Therefore, F_{frict} = 5.32 N, left. The coefficient of friction can now be determined as the ratio of friction force to normal force.

The unit for friction is the **Newton** (N).

FN is the **normal force**. As is indicated by the equation, it is actually the normal force, not the weight, that is responsible for friction. Classification of Friction Forces. You will explore two classifications of friction forces.

Example: Using the friction loss calculator

For the material, a copper pipe, C = 135. H_{L} = 2.868 m of water. **P _{d} = 2.868 * 9810 = 28135.08 N/m^{2} = 0.28 bar** . This implies the pressure drop in the flow due to pipe friction is 0.28 bar .

**Add up all the numbers and divide by the population size:**

- Mean (μ) = ΣX/N, where Σ is the summation (addition) sign, x
_{i}is each individual number, and N is the population size. - In the case above, the mean μ is simply (12+55+74+79+90)/5 = 62.
