Resultant Force Formula:
| From: | To: |
The resultant force is the single force that represents the vector sum of multiple forces acting on an object. In 2D space, it combines the x and y components of all forces into one net force with both magnitude and direction.
The calculator uses the Pythagorean theorem to calculate the magnitude of the resultant force:
Where:
Explanation: The equation calculates the hypotenuse of a right triangle where the two perpendicular sides represent the force components in x and y directions.
Details: Calculating resultant force is fundamental in physics and engineering to determine the net effect of multiple forces acting on an object. It's essential for analyzing motion, designing structures, and solving statics and dynamics problems.
Tips: Enter the force components in newtons (N) for both x and y directions. The calculator will compute the magnitude of the resultant force. Both positive and negative values are acceptable as they indicate direction.
Q1: How do I find the direction of the resultant force?
A: The direction (angle θ) can be calculated using θ = arctan(Fy/Fx). This gives the angle relative to the x-axis.
Q2: Can this calculator handle more than two forces?
A: This version calculates the resultant of two perpendicular components. For multiple forces, you would first need to find the sum of all x-components and y-components separately.
Q3: What if my forces are not perpendicular?
A: For non-perpendicular forces, you need to resolve each force into its x and y components before using this calculator.
Q4: What units should I use?
A: The calculator uses newtons (N) as standard units. Make sure all inputs are in consistent units.
Q5: How accurate is this calculation?
A: The calculation is mathematically exact for the given components. Rounding may occur in the displayed result.
