explain Newton's 1st law in relation to forces, balanced forces and unbalanced forces
Multiple Post. Please refer to your later post, which I saw first.

Newton's first law, also known as the law of inertia, states that an object at rest will stay at rest, and an object in motion will continue to move at a constant velocity (speed and direction) unless acted upon by an external force.
To understand this law in relation to forces, it is important to understand the concepts of balanced forces and unbalanced forces.
Balanced forces occur when two or more forces acting on an object cancel each other out, resulting in no change in the object's motion or its state of rest. In other words, the net force is zero. According to Newton's first law, if the net force on an object is zero (balanced forces), the object will remain at rest if it was initially at rest, or it will continue moving with a constant velocity if it was already in motion.
On the other hand, unbalanced forces occur when the forces acting on an object do not cancel each other out. In this case, there is a net force acting on the object, causing it to accelerate or decelerate depending on the direction of the net force. Again, according to Newton's first law, if the net force is non-zero (unbalanced forces), the object will experience a change in its motion. It will either start moving if it was initially at rest or change its speed and/or direction if it was already in motion.
So, Newton's first law relates to forces by stating that an object will maintain its state of rest or motion unless an external force acts upon it. Balanced forces result in no change in motion, while unbalanced forces cause a change in motion.
