How do you find acceleration with force and coefficient of friction?

The friction force depends on the mass of an object plus the coefficient of sliding friction between the object and the surface on which it slides. Subtract this force from the applied force to find the acceleration of the object.

How do you find the force of friction with a coefficient?

How to find force of friction

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

Does the coefficient of friction change with force?

The coefficient of friction should in the majority of cases, remain constant no matter what your normal force is. When you apply a greater normal force, the frictional force increases, and your coefficient of friction stays the same.

Does the coefficient of friction change with acceleration?

Friction always acts in the direction opposing motion. This means if friction is present, it counteracts and cancels some of the force causing the motion (if the object is being accelerated). That means a reduced net force and a smaller acceleration. More friction and the puck slows to a stop faster.

What changes the coefficient of friction?

a) The materials that are in contact. The two materials and the nature of their surfaces. Rougher surfaces have higher coefficient of frictions but to slide apart. Pushing the surfaces together causes the more of the asperities to come together and increases the surface area in contact with each other.

What affects the coefficient of friction?

The frictional force between two bodies depends mainly on three factors: (I) the adhesion between body surfaces (ii) roughness of the surface (iii) deformation of bodies.

How does friction affect the net force on an object?

How does friction affect the net force on an object? When surfaces slide or tend to slice over one another, a force of friction acts. When you apply a force to an object, friction usually reduces the net force and the resulting acceleration.
