# Static Friction Calculator

Static Friction refers to the friction or force between two object in contact that are not moving. Static friction is greater than kinetic friction. Static friction is that force which resists the beginning of sliding motion of one body over the other body. Static Friction is also known as limiting friction or starting friction. The Static friction is denoted by the symbol ‘Fs’. The SI unit of static friction is ‘N’- Newton Meter. The Static Friction normally takes place on the electromagnetic level. The Static frictional force is said to be a self-adjusting force. i.e., the static friction will always be equal and opposite to the force applied.
Static Friction Calculator
 I want to calculate: --Select-- Static Friction Coefficient Normal Force Static Friction Static Friction Coefficient (μs): Normal Force (N): N Static Friction (Fs): N
Formula
Static Friction :
Fs = μs *N

Static Friction Coefficient :
μs = Fs/N

Normal Force :
N = Fs/μs

Where,
μs = Static Friction Coefficient,
N = Normal Force.

The Static Force is required to move one of the bodies among the two when they are at rest. This advanced online Static Friction Calculator is used to calculate and find the static friction between two objects that do not move when static friction coefficient and normal force are known.

Example:
Calculate the Static friction for the given details of the object.
Static Friction Coefficient (μs) = 25
Normal Force (N) = 20 N

Solution:
Apply Formula:
Fs = μs *N
Fs = 25*20
Fs = 500 N

Static Friction (Fs) = 500 N
