Calculate the balance force

1. No, the two forces are not equal

2. To put it simply: an object is originally balanced, but it is still balanced after being subjected to two more forces (static or uniform linear motion). These two forces are balanced forces. The interaction force is that you give me a force and I also give you a force. Reciprocity

3. 1. According to Newton's first law, the pulling force is equal to gravity = 10 ^ 4N
2, the decelerating descent F1 > F2
3, the resistance = traction 2000N
the resistance = 0n

4. The equilibrium forces counteract each other, which is equivalent to being free from external forces. Therefore, there is a saying that "when a body is subjected to a balanced force, it is still or moving in a straight line at a constant speed.". In fact, the balance force is a pair of external forces that counteract each other. The balance force is an external force. I wonder if I have made it clear?

5. The balance point between planets is "Lagrange point". You can search this keyword directly on the Internet. The following website is a calculation method of Lagrange point. I hope it can help you http://ljm.693.blog.163.com/blog/static/58279231201110129127450/

6. I don't know what your so-called balance force is
in SW motion, extracting the force on the fixed constraint should be the so-called balance force

7. When a person moves in a straight line at a constant speed, he is not forced, or the force is a balancing force. So it's a balancing force. The two forces are balanced, and the magnitude of the two forces can not be different.

8. Count,

9. Take two objects as a whole, the internal force between them is a pair of mutual forces, equal reverse collinear, the resultant force is zero.
