Friction Force Calculator

The friction force calculator is the tool that will help you determine the magnitude of friction force for situations like pushing or pulling an object along the floor. But before we get into friction force calculations, this accompanying article will help you understand what friction force is and why this friction force is both desirable and undesirable.

Friction is a phenomenon that arises when two surfaces are in contact. The force acting as a resistance to the movement of the objects slides against each other. It could be either solid on solid or fluid on solid. There are different types of friction based on the scenarios. Mathematically, the friction force, $F$ acting on the body, is the product of the coefficient of friction $\mu$ and the normal force $N$ acting on the object. Such that:

Friction is one of the components responsible for creating the difference between "ideal" and "actual" conditions. In other words, the phenomenon is one of the causes why the output is always less than the input. For instance, the friction between gears, pistons, and the sliding mechanism causes energy loss resulting in lower outputs. In such cases, the frictional force is undesirable and must be reduced. However, the vehicle brakes operate on friction (refer stopping distance calculator), and therefore it is desirable in such cases.

Let's perform the frictional force calculations for an object being pushed along the floor with a normal force of $75$ N. Consider the coefficient of friction as $0.2$.

1. Enter the coefficient of friction as $0.2$.
2. Fill in the value of normal force as $75$ N.
3. The frictional force calculator will return
