1. What is Angle of Net Force?

Definition: The angle of net force is the direction of the resultant force when two perpendicular forces (horizontal and vertical) act on an object.

Purpose: This calculation is essential in physics and engineering to determine the direction of the resultant force acting on an object.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ θ = \arctan\left(\frac{F_y}{F_x}\right) \]

Where:

\( θ \) — Angle of net force (degrees)
\( F_y \) — Vertical force component (Newtons)
\( F_x \) — Horizontal force component (Newtons)

Explanation: The arctangent function calculates the angle whose tangent is the ratio of vertical to horizontal force.

3. Importance of Angle Calculation

Details: Knowing the angle of net force helps in analyzing motion direction, designing structures, and solving force equilibrium problems.

4. Using the Calculator

Tips: Enter both force components in Newtons. The calculator handles positive and negative values to determine the correct quadrant for the angle.

5. Frequently Asked Questions (FAQ)

Q1: What happens if F_x is zero?
A: When horizontal force is zero, the angle is 90° (if F_y is positive) or 270° (if F_y is negative).

Q2: How are negative forces handled?
A: Negative values indicate opposite directions. The calculator uses atan2 function to determine the correct quadrant.

Q3: What's the range of possible angles?
A: The angle ranges from -180° to +180° (or 0° to 360° in some systems).

Q4: Can I use this for 3D forces?
A: No, this is for 2D forces only. For 3D, you'd need additional calculations.

Q5: How precise is the calculation?
A: The result is precise to two decimal places, sufficient for most applications.
