- The Law of Parallelogram of Forces is a physics concept that states that the resultant of two non-collinear concurrent forces can be found by representing them as adjacent sides of a parallelogram
- The magnitude of the resultant force is given by the equation R² = P² + Q² + 2PQ cosθ
- The Triangle Law of Forces is a corollary of the Parallelogram Law and states that the resultant force is the vector directed from the tail of the first vector to the tip of the second vector
- Examples of using the Parallelogram Law and the Triangle Law are provided with calculations and solutions
- Both laws are used to find the resultant of forces and the angle they make with the horizontal, providing solutions using the cosine rule and other mathematical equations to calculate the resultant force and angle.
