Question

The expression:

"If the vector sum of the external forces on a system is zero, the total linear motion of the system ..."

Complete the sentence with the best option that completes the expression:

a) It is constant and the utility lies in that it does not depend on the detailed nature of the internal forces acting between the members of the system.

b) It is constant and the utility lies in that it depends on the detailed nature of the internal forces acting between the members of the system.

c) It is not constant and the utility lies in that it depends on the detailed nature of the external forces acting between the members of the system.

d) It is not constant and the usefulness is that it does not depend on the detailed nature of the external forces acting between the members of the system.

Expert Solution
Step 1

When the vector sum of all the external forces are zero this means net acceleration of the object is zero.

which implies the object's velocity (motion) does not change and remains constant.

also motion of the object does not depend on the detailed nature of internal forces acting between the members of the system.
