How are the new laws I published yesterday related to Issac Newtons laws of gravity ? Newton discovered the inverse square law for distance in terms of the force of gravity. He deduced the inverse square law from Kepler's third law and the formula for a force in a circular orbit :
F 𝞪 V sq / R
We can now try a different route to Newton by replacing V squared with my second law :
• Velocity = √ Distance / Distance
F 𝞪 (√ R / R) ^2 / R
F 𝞪 (R / R^2) / R = (1/R) / R = 1/R^2
F 𝞪 1 / R sq
We have arrived at Newton's inverse square law.
We can then combine Newton's inverse square law and my first law :
• Distance squared = Time / Velocity
F 𝞪 1 / (T / V)
F 𝞪 V / T
So the force of gravity is proportional to the velocity divided by the orbital period.
In the last article, I mentioned about doubling the distance and it's impact on velocity and the orbital period for mars relative to venus. This time let's work it out exactly :
• V = √ D / D
V = √2 / 2
V = 0.707
• D sq = T / V
4 = T / 0.707
T = 4 x 0.70 = 2.828.
So when the distance from the Sun is doubled the velocity of the more distant planet reduces by 30% and the orbital period increases by a factor of 2.82. Now lets put this into the formula above :
F 𝞪 V / T
F 𝞪 0.707 / 2.828
F 𝞪 0.25
This once again leads us to Newton's inverse square law for gravity which shows that when you double the distance from the Sun, the force of gravity is reduced to a quarter or 25% of its original strength.
F 𝞪 1 / (T / V)
F 𝞪 V / T
So the force of gravity is proportional to the velocity divided by the orbital period.
