Question

why is the net force approximately equal to or similar to the body’s weight divided by 2 (at least according to my physics textbook) ? I mean, why a straightforward approximation like that ? What is the thought process behind it ? Is it just an empirical evidence or has a concept underlying it ?

Answer 1

The net force is approximately equal to the body's weight divided by 2, based on Newton's second law of motion.

Step-by-step explanation:

In physics, the net force acting on an object is approximately equal to or similar to the body's weight divided by 2. This is based on Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net external force and inversely proportional to its mass. By dividing the body's weight by 2, we are estimating the net force acting on the object.
