Calculate Normal Force







Formulas

The formulas to calculate the normal force (Fn) are:

\[ F_{n} = \frac{F_{f}}{C_{f}} \]

and

\[ F_{n} = F \cdot \sin(\theta) \]

Where:

What is Normal Force?

Normal force is the force perpendicular to the surface that an object contacts. It is a reaction force that prevents objects from "falling" into whatever they are in contact with. It can be calculated using the force due to friction and the coefficient of friction, or using the total force and the angle at which the force is applied.

Example Calculation

Let's assume the following values:

Using the formulas to calculate the normal force:

\[ F_{n} = \frac{50}{0.5} = 100 \text{ N} \]

and

\[ F_{n} = 100 \cdot \sin(30°) = 100 \cdot 0.5 = 50 \text{ N} \]

The Normal Force (Fn) using friction is 100 N, and using the angle is 50 N.
