Question

If $F_1$and $F_2$are two forces simultaneously acting on an object, the vector sum $F_1+F_2$is called the _________ force.

Short answer

If $F_1$and role="math" localid="1646818655101" $F_2$ are two forces simultaneously acting on an object, the vector sum role="math" localid="1646818667992" $F_1+F_2$ is called the resultant force.

Step-by-step solution

Step 1 Definition for Force:

A force is a vector quantity which is having both its magnitude and direction. Forces are always represented by vectors, thus the same algebraic operations are also applied on two forces.

Step 2 Definition for the resultant force:

The combined forces are equal to two forces, applying on a body is denoted as their sum and such force is called as resultant force as it effects the same on the body as other two forces effect. Thus in simple we can say that, if$F_1$and$F_2$are two forces simultaneously acting on an object the vector sum$F_1+F_2$is called as the resultant force.
