Question

What is the resultant force

Answer 1

A resultant force is the single force and associated torque obtained by combining a system of forces and torques acting on a rigid body. The defining feature of a resultant force, or resultant force-torque, is that it has the same effect on the rigid body as the original system of forces.

Answer 2

an object may have several different forces acting on it which can have different strengths and directions. but they can be added together to give aresultant force. this is the single forcethat has the same effect on the object as all the individual forces acting.
