__Friction Force Formula:__

Friction force (F) is a fundamental concept in physics, describing the force that resists the motion of one surface relative to another.

It plays a critical role in everyday life and in various engineering and scientific applications, such as in mechanical systems, automotive braking, and the design of sportswear and equipment.

The force of friction is derived from the interaction of the surface irregularities of the two materials in contact.

Friction force, F_{(N)} in Newtons is calculated by the product of coefficient of friction, u and normal force, N_{(N)} in Newtons.

Friction force, F_{(N)} = u * N_{(N)}

F_{(N)} = friction force in Newtons, N.

u = coefficient of friction.

N_{(N)} = normal force in Newtons, N.

__Friction Force Calculation:__

- Calculate the friction force for a box sliding on a wooden floor:

Given: u = 0.5, N_{(N)} = 200 newtons (N)

Friction force, F_{(N)} = u * N_{(N)}

F_{(N)} = 0.5 * 200

F_{(N)} = 100N.

- Determine the normal force required to keep a vehicle from sliding on an icy road, given a known friction force:

Given: u = 0.1, F_{(N)} = 300 newtons (N)

Friction force, F_{(N)} = u * N_{(N)}

N_{(N)} = F_{(N)} / u

N_{(N)} = 300 / 0.1

N_{(N)} = 3000N.
