Gravitational Force (Science In Vedas)

यदा ते हर्यता हरी वावृधाते दिवेदिवे |
आदित्ते विश्वा भुवनानि येमिरे || —Rigveda [8.12.28]

O Indra! by putting forth ur mighty rays, which possess the qualities of gravitation n attraction-illumination n motion–

keep up the netire universe in order through the Power of your attraction.”

The purport of the following richa is that all heavenly bodies are attracted by the sun, and the sun together with the other spheres is upheld by the attracting power of ईश्वर.

The verse is capable of two interpretations according as the word Indra is taken to mean ईश्वर or the सुर्य. in the original the two interpretations are given together, but we have taken the liberty to give them separately dor the sake of greater clearness...

The glorious sun, by putting forth his powerful rays which possess the properties of attraction, illumination n motion, keeps all the worlds in order through the force of his attraction. Rig VI.1.6.3.

It is for this reason that the heavenly bodies don't deviate frm their orbits.

The following also contains the science of attraction.

आदह स्वधामनु पुनर्गर्भत्वमेरिरे| दधाना नाम यज्ञियम्|| —Rig[1-6-4]

O Glorious and Mighty Lord! (or the Glorious sun!) when they mortal (in the one case) and aerial (in the other) subjects obey thy law of support (in the one)

And of attraction (in the other) then alone all the worlds are rendered firm and habitable. This is the reason why they move in their appointed orbits.

The next richa also says the same:

वीळु चिदारुजत्नुभिर्गुहा चिदिन्द्र वह्निभिः |
अविन्द उस्रिया अनु || —Rigveda [1-6-5]

यदा सूर्यममुं दिवि शुक्रं ज्योतिरधारयः ।
आदित्ते विश्वा भुवनानि येमिरे ॥ — Rigveda 8.12.30

“O Ishwar, You have created this Sun. You possess infinite power. You are upholding the sun and other spheres and render them steadfast by your power of attraction.”

The next Yajurvedic Richa also contains the science of attraction. The Supreme Lord (or the sun) is upholding all spheres with His(or his) glorious(or brilliant) power of attraction and with the gift of knowledge(or light) which makes the happiness-producing activities possible.

आ कृ॒ष्णेन॒ रज॑सा॒ वर्त्त॑मानो निवे॒शय॑न्न॒मृतं॒ मर्त्यं॑ च | हि॒र॒ण्यये॑न सवि॒ता रथे॒ना दे॒वो या॑ति॒ भुव॑नानि॒ पश्य॑न् ||

—Yajurveda 33.43

“The sun moves in its own orbit in space taking along with itself the mortal bodies like earth through force of attraction.”

हिरण्यपाणिः सविता विचर्षणिरुभे द्यावापृथिवी अन्तरीयते। अपामीवां बाधते वेति सूर्यमभि कृष्णेन रजसा द्यामृणोति॥ Rigveda 1-35-9

The sun moves in its own orbit but holding earth and other heavenly bodies in a manner that they don't collide with each other through force of attraction.

पञ्चारे चक्रे परिवर्तमाने तस्मिन्ना तस्थुर्भुवनानि विश्वा | तस्य नाक्षस्तप्यते भूरिभारः सनादेव न शीर्यते सनाभिः ||
—Rig Veda 1.164.13

Sun moves in its orbit which itself is moving. Earth n other bodies move around sun due to force of attraction, because sun is heavier than them.

The above is only a sample, there are lots more similar references.
