Answer:
the vector sum of all such forces which equals zero for an object at rest. CASE 1: Considering a basketball of weight 1kg, if it has been kept stationary on the ground, there are two forces acting on it. These are it's weight (gravity) and equal and opposite force from the ground (normal reaction).

An object is moving across a surface, but it does not gain or lose speed, the object’s net force is zero.
Explanation:
- The net force means the vector sum of all the forces acting on an object.
- When an object is in equilibrium, either the object at rest or moving with constant velocity, the net force acting on it zero.
- A vector can only have zero magnitude if all of its components are zero.
- In other words, if there is no net force on an object, its speed and direction of motion do not change.
- Including if the object at rest, the net force is zero.
- An unbalanced force acting on an object changes its speed and/or direction of motion.
- However, the forces are balanced and there is no net force the object will not accelerate and the velocity will remain constant.
