When reasultant of all forces acting on a body is zero, the forces are called

When the resultant of forces acting on a body is not Zero, what are they called?

Statement-1: If the resultant of all the forces acting on a system is zero then the torque on the system about any point is same. Statement-2: If the resultant of the forces acting on a system is zero then acceleration of its centre of mass is zero.

The force acting on a body it is a rest

If the resultant torque of all the forces acting on a body is zero about a point is it necessary that it will be zero about any other point?

If the resultant torque of all the forces acting on a body is zero about a point is it necessary that it will be zero about any other point?

If the resultant torque of all the forces acting on a body is zero about a point is it necessary that it will be zero about any other point?

If the sum of all the forces acting on a body is zero, is it necessarily in equilibrium ? If the sum of all the forces on a particle is zero, is it necessarily in equilibrium?
