Resultant Force Formula
The resultant force formula is the formula that calculated the resultant of all the force acting on the body. If F1, F2, F3,… are the forces acting on a body, the resulting force RF is calculated using the formula with positive and negative signs used for pair of opposite forces.
FR = F1 + F2 + F3 . . .
where,
F1, F2, F3, . . . are the linear forces acting of the body
If F1 and F2 are the forces perpendicular to each other then their resultant force is given using the formula,
FR = √(F12 + F22)
The consequence can be calculated geometrically using the triangle law, parallelogram law, or polygon law of vector addition, depending on the number of forces operating.
It’s worth noting that unless the forces are collinear, they can’t be added or subtracted.
Resultant Force
Resultant Force is the total force acting on the body. It is defined as the sum of all forces acting on a body and it is the vector sum of all the forces acting on a body. The resultant force is measured in Newton which is the SI unit of force. If the resultant force acting on a body is zero then either it is in uniform motion or it is at rest.
The resultant force acting on an object can be visualized by the example, suppose a box is resting on a table and the force of 10 N is applied to it in the North direction and a force of 8 N is applied to it in the south direction then the resultant force acting on the body is in 2 N (10 N – 8 N).
In this article, we will learn about, force, the resultant force, and the resultant force formula, its example, and others in detail. Now before learning about the resultant let’s learn about What is Force?
