Question

definition of parallelogram of force.

Answer 1

a parallelogram illustrating the theorem that if two forces acting at a point are represented in magnitude and direction by two sides of a parallelogram meeting at that point, their resultant is represented by the diagonal drawn from that point.

Answer 2

Force when applied on a rigid body use only the motion in it well when applied on a non rigid body can cause both the change in its size or shape and the motion in intimate in the mathematical form force applied on a body is defined as the rate of change in the linear momentum for example force is a vector quantity and its SI unit is Newton symbol in a Kilogram force symbol KGF over 1 KGF is equal to gnf G is the acceleration due to gravity is equal to 9.8 ms-2 on average....!!!!!!!!!!!!!!!

Hope it helps....!!!!!!!!!!!!!!!!
