Friction Calculator

If you want to determine the force of friction between the ground and an object, then you can use this friction calculator.

In physics, resistance is the opposition to an object's motion that stops an object from moving further. However, like gravity, resistance isn't a fundamental force. But instead, according to scientists, it's an electromagnetic attraction among charged particles between the two joining surfaces.


Formula of Friction Calculator

If you want to calculate the friction between two touching surfaces instantly, you can use our friction calculator, or to find it manually, you can use the formula listed below:

F = μN


F = frictional force (where friction force calculator can help to find simple force in Newton)

μ = dimensionless coefficient of friction

N = Normal force (which is at an angle of 90 degrees and said to be the perpendicular line to the surface of the ground)


To calculate efficiency, you can use our Efficiency Calculator.


For a more precise understanding of concepts, let us have an example below:

Suppose a cart is acting 250N of force to move on the ground, where and the coefficient of friction is 0.13; find the frictional force that's resisting the cart to proceed further.

Given data

Force = N = 250 N
Dimensionless coefficient of friction = μ = 0.13

To Find

Frictional force = ?


To find the frictional force, we will use the formula listed below:

F = μN

Putting values in the formula:

F = (250 N) * 0.13 = 32.5 N
