Net force is the overall force acting on an object, taking into account both magnitude and direction. It is calculated by adding all the individual forces acting on an object together, taking into account their respective directions.
According to Newton's first law of motion, an object will remain at rest or continue moving at a constant velocity unless acted upon by a net force. Therefore, net force is responsible for changing an object's state of motion.
Yes, net force can be zero if all the forces acting on an object cancel each other out. This means that the object will either remain at rest or continue moving at a constant velocity.
If the net force on an object is not zero, the object will accelerate in the direction of the net force. The magnitude of the acceleration will depend on the mass of the object and the magnitude of the net force.
The net force on an object can be changed by altering the magnitude or direction of one or more of the individual forces acting on the object. This can be done by applying a new force, changing the direction of an existing force, or adjusting the strength of an existing force.
