removed from the formula.

2. When the object being pulled is a planet, planet or moon, the
final net force is Fg1-Fg2, because the object being pulled also
has its gravity.

3. / R ratio / (R ^ 2) is more effective and easier to understand.
Because the physical formula is through a proportional and

inverse relationship, many can be accepted by the formula.

6.7 Rewriting inertia Moment of Inertia
1. Mechanics: Rewriting the inertia Moment of Inertia,

R = radius M = mass V = speed
Moment of Inertia Inertia = angular kinetic momentum / angular
velocity = (RMV) / (angle / time) = RM R (angle / time) / (angle

/ time) = M (R ^ 2)

6.8 Rewriting the spring energy,
2 work = force (distance) = (kx) (x) = kx^2 not 1/2 kx^2

F= force x = distance F= kx k= elastic coefficient
The KX force should also be divided into Tensile Force or Or
Compression Force. There is currently no distinction.

6.9
E = mc ^ 2 is wrong.
1. When energy = force (distance) = mass (acceleration)

(distance), E = m (c ^ 2) Error:: Acceleration cannot be
decomposed into velocity/time, and time is shifted to x to make

it squared. This is wrong.
So E = mc ^ 2 is wrong.

6.10 Questioning the energy in relativity

E = mc ^ 2 /(1-v ^ 2 / c ^ 2)^ 1/2 when expanded (1-v ^ 2 / c ^
2)^ 1/2 =(C ^ 2-V ^ 2 / C ^ 2)^ 1/2 It wants to express (C-V) /
C;; C = speed of light v = speed

When the speed reaches the speed of light, the energy is infinite.
Why energy is infinite and the speed of light is limited. Since
