Class 9 Physics in Hindi: अध्याय-वार विषय (What Each Chapter Covers)
अध्याय 4 — अपने परिवेश में गति का वर्णन
सरल रेखा में गति: स्थिति का वर्णन, चली गई दूरी और विस्थापन, माध्य चाल एवं माध्य वेग, माध्य त्वरण। गति का आलेखीय निरूपण: स्थिति-समय ग्राफ और वेग-समय ग्राफ। नियत त्वरण से गति के लिए गति के समीकरण, और एकसमान वृत्तीय गति।
अध्याय 6 — गति पर बलों का प्रभाव
बल की अवधारणा और बल को मापना, संतुलित एवं असंतुलित बल, घर्षण बल, न्यूटन के गति के तीनों नियम, और वस्तुओं के निकाय पर लगने वाले बल।
अध्याय 7 — कार्य, ऊर्जा एवं सरल मशीनें
नियत बल द्वारा किया गया कार्य (शून्य, धनात्मक और ऋणात्मक कार्य), ऊर्जा के रूप, यांत्रिक ऊर्जा — गतिज ऊर्जा, स्थितिज ऊर्जा और यांत्रिक ऊर्जा का संरक्षण, शक्ति, और सरल मशीनें — घिरनी, आनत तल और उत्तोलक।
अध्याय 10 — ध्वनि तरंगें: अभिलक्षण एवं अनुप्रयोग
ध्वनि का उत्पादन और संचरण, ध्वनि तरंगें (संपीडन और विरलन), ध्वनि तरंगों की ऊर्जा, तरंगदैर्ध्य, आवृत्ति, आवर्तकाल, आयाम और तीव्रता, ध्वनि की चाल, मानव द्वारा ध्वनि-बोध, ध्वनि का परावर्तन (प्रतिध्वनि और अनुरणन), तथा पराश्रव्य और अवश्रव्य तरंगें और उनके अनुप्रयोग।
Important Formulas – Class 9 Physics in Hindi
These are the main formulas from the four chapters of the NCERT Class 9 Physics Book PDF in Hindi.
अध्याय | सूत्र (Formula) | अर्थ |
|---|---|---|
4 | v = u + at | पहला गति समीकरण |
4 | s = ut + ½at² | दूसरा गति समीकरण |
4 | v² = u² + 2as | तीसरा गति समीकरण |
6 | F = ma | न्यूटन का दूसरा नियम (बल = द्रव्यमान × त्वरण) |
7 | W = F × s | कार्य = बल × विस्थापन (बल की दिशा में) |
7 | KE = ½mv² | गतिज ऊर्जा |
7 | PE = mgh | स्थितिज ऊर्जा |
7 | P = W / t | शक्ति = कार्य ÷ समय |
10 | v = λν | ध्वनि की चाल = तरंगदैर्ध्य × आवृत्ति |
10 | T = 1/ν | आवर्तकाल = 1 ÷ आवृत्ति |
Hindi–English Physics Terms (हिंदी–अंग्रेज़ी शब्दावली)
Learning both names now helps in Class 11 and in NEET or JEE, which can be taken in Hindi or English.
हिंदी | English |
|---|---|
विस्थापन | Displacement |
वेग / त्वरण | Velocity / Acceleration |
एकसमान वृत्तीय गति | Uniform circular motion |
संतुलित / असंतुलित बल | Balanced / Unbalanced force |
घर्षण | Friction |
गतिज / स्थितिज ऊर्जा | Kinetic / Potential energy |
शक्ति | Power |
घिरनी / आनत तल / उत्तोलक | Pulley / Inclined plane / Lever |
संपीडन / विरलन | Compression / Rarefaction |
तरंगदैर्ध्य / आवृत्ति / आयाम | Wavelength / Frequency / Amplitude |
प्रतिध्वनि / अनुरणन | Echo / Reverberation |
पराश्रव्य / अवश्रव्य | Ultrasonic / Infrasonic |
Old vs New Class 9 Physics Chapters
The NCERT Class 9 Physics Book PDF in Hindi has changed. The old book had 5 Physics chapters; the new अन्वेषण book has 4.
पुराना अध्याय (up to 2025-26) | नया अध्याय (2026-27) |
|---|---|
8 – गति | अध्याय 4 – अपने परिवेश में गति का वर्णन |
9 – बल तथा गति के नियम | अध्याय 6 – गति पर बलों का प्रभाव |
10 – गुरुत्वाकर्षण | अलग अध्याय नहीं (No separate chapter) |
11 – कार्य तथा ऊर्जा | अध्याय 7 – कार्य, ऊर्जा एवं सरल मशीनें (सरल मशीनें जोड़ी गईं) |
12 – ध्वनि | अध्याय 10 – ध्वनि तरंगें — अभिलक्षण एवं अनुप्रयोग |
If your guide still has गुरुत्वाकर्षण as a chapter, it follows the old syllabus. Check the latest CBSE Class 9 syllabus.
How to Study Class 9 Physics in Hindi Medium
Use these steps with the NCERT Class 9 Physics Book PDF in Hindi, one chapter at a time.
- Graphs first in अध्याय 4. Practise drawing स्थिति-समय and वेग-समय ग्राफ; many questions are based on reading a graph.
- Write units with every answer — मीटर (m), न्यूटन (N), जूल (J), वाट (W), हर्ट्ज़ (Hz).
- Solve every in-text question in the NCERT Class 9 Physics Book PDF in Hindi before the chapter-end exercises.
- Revise and test for class 9 physics hindi medium with eSaral's Class 9 revision notes, NCERT Solutions for Class 9 Science and the Class 9 and 10 test series.
💡 Expert Tip by eSaral Physics Faculty For every numerical in the NCERT Class 9 Physics Book PDF in Hindi, write three lines first: दिया है (given), ज्ञात करना है (to find) and सूत्र (formula). This habit alone removes most calculation mistakes.

No. The NCERT Class 9 Physics Book PDF in Hindi is part of the Hindi-medium science textbook अन्वेषण. Its Physics chapters are 4, 6, 7 and 10.
How many Physics chapters are there in Class 9 Science (अन्वेषण)?
There are four Physics chapters: अपने परिवेश में गति का वर्णन (Chapter 4), गति पर बलों का प्रभाव (Chapter 6), कार्य, ऊर्जा एवं सरल मशीनें (Chapter 7) and ध्वनि तरंगें — अभिलक्षण एवं अनुप्रयोग (Chapter 10).
Is गुरुत्वाकर्षण (Gravitation) still in Class 9 Physics?
Not as a separate chapter. The new अन्वेषण book has no गुरुत्वाकर्षण chapter; the old 5-chapter list is no longer used.
What is new in Class 9 Physics in Hindi for 2026-27?
The book is new (अन्वेषण), the chapters are renumbered (4, 6, 7, 10) and गुरुत्वाकर्षण is no longer a chapter. अध्याय 7 also adds सरल मशीनें — घिरनी, आनत तल और उत्तोलक.
Where can I download the NCERT Class 9 Physics Book PDF in Hindi for free?
eSaral links all four Physics chapters of अन्वेषण directly from the official NCERT website in the table on this page. No login is needed.
Is Class 9 Physics in Hindi useful for NEET or JEE?
Yes. Motion, Newton's laws, work-energy and waves return in Class 11 Physics. eSaral teachers suggest learning each Hindi term with its English name early, because NEET and JEE Main can be taken in Hindi or English.
