## What is the coefficient of friction between the block and the table?

Coefficient of friction between the block and table is μ=0.5. The system is released from rest.

## How do you find the coefficient of friction for a sliding block?

As P is continually increased, the block will now slip, with the friction force acting on the block being: f = muK*N, where muK is the coefficient of kinetic friction, with f remaining constant thereafter as P is increased.

**How do I calculate the coefficient of friction?**

The formula to calculate the coefficient of friction is μ = f÷N. The friction force, f, always acts in the opposite direction of the intended or actual motion, but only parallel to the surface.

**What is the coefficient of friction between the block and the floor?**

In figure, the coefficient of static friction between the floor and block B is 0.30.

### What is the coefficient of friction between the block and the horizontal surface?

mu

The coefficient of friction between the block and the horizontal surface is mu. The block moves. The coefficient of friction between the block and the horizontal surface is mu. The block moves toward right under action of horizontal force `F` (figure-a).

### What is the coefficient of static friction between the two blocks?

The coefficient of static friction is 0.60 between the two blocks in figure. The coefficient of kinetic friction between the lower block and the floor is 0.20. Force F⃗ causes both blocks to cross a distance of 5.0m , starting from rest.

**What is the coefficient of kinetic friction between the block and the surface?**

The coefficient of friction for surfaces between block and plank is 0.5, whereas friction between plank and underneath surface is negligible. Find the friction between block and plank.

**What is the coefficient of kinetic friction between the block and the ramp?**

The coefficient of kinetic friction between the block and the plan is 0.2. The block goes up the ramp, momentarily comes to rest, and then slides back down the ramp.

## What is the coefficient of static friction between block and plank?

The coefficient of friction between the block and the plank is π=31. If a horizontal force F is applied in the plank, then the maximum value of F for which the block and the plank move together is (g=10m/s2)

## Is the force of the string on B larger than smaller than or equal to the force of the hand on a?

The hand must accelerate both blocks A and B, so more force is required to accelerate the greater mass. Thus the force of the string on B is smaller than the force of the hand on A.

**What is the coefficient of friction between the block and surface?**

μ – Coefficient of friction between the block and the surface, for Static friction it is termed a μ s and for kinetic or sliding friction it is termed as μ s or μ k .

**What is the static friction coefficient?**

The static friction coefficient (μ) between two solid surfaces is defined as the ratio of the tangential force (F) required to produce sliding divided by the normal force between the surfaces (N)

### What is the relationship between normal force and coefficient of friction?

The friction force, F, is proportional to the normal force, N, and the coefficient of friction, μ : where μ s is the coefficient of static friction and μ k is the coefficient of kinetic friction. The value of μ s is generally higher than the value of μ k for a given combination of materials.

### How can I determine the coefficient of friction between materials?

Coefficients of friction between materials are best determined through testing. However, it is possible to find tables in the literature for friction coefficients between various materials. We have collected some of those tables here. The table below is from Barrett, “Fastener Design Manual,” NASA Reference Publication 1228, 1990 :
