Question

if the sum of all forces acting on the object is equal to zero, forces are said to be ​

Answer 1

Answer:

The net force is the vector sum of all the forces that act upon an object. That is to say, the net force is the sum of all the forces, taking into account the fact that a force is a vector and two forces of equal magnitude and opposite direction will cancel each other out

Answer 2

If the sum of all forces acting on the object is equal to zero, forces are said to be balanced.

Explanation:

Net force is classified as : Balanced force and Unbalanced force.

Unbalanced Force

• When the force of direction is applied only in one direction, the net force is non-zero.
• Or when the forces acting on each side is not equal, then the net resultant force decides the direction of motion.
• There is acceleration in the system as a result of non zero resultant force.

Balanced Force

• In the case of balanced force, the body is acted upon by forces in opposite direction.
• When equal forces act in each direction, it results in zero net force. And the body remains in equilibrium state.
• There is no acceleration in the body.
• If it was initially at rest, it remains at rest and if it was in motion, it remains in constant motion.
