क्या आप किसी सब्जेक्ट की पढ़ाई में कमजोर हैं? या आपको भी कोई सब्जेक्ट पढ़ने में इंटरेस्ट कम आता है 

Are you weak in studying any subject? Or do you also have less interest in studying any subject? 

आइये समझते हैं ऐसा क्यों होता है 

Let's understand why this happens 

इसके दो प्रमुख कारण हैं  There are two main reasons for this 

१ आपकी उस सब्जेक्ट  को पड़ने की इच्छा का ना होना  1 Your lack of desire to study that subject 

२ सब्जेक्ट को पढ़ाने वाला ठीक ना मिला हो  2 You may not have found the right teacher to teach the subject.  

तो पहला पॉइंट के लिए आपको मोटिवेशन की जरुरत है   So for the first point you need motivation 

और दूसरे पॉइंट के लिए बात करें फिजिक्स सब्जेक्ट की तो इसकी जिम्मेदारी हम लेंगे  And for the second point, if we talk about Physics subject then we will take responsibility for it.  

फिजिक्स आप हमारे चैनल से समझ सकते हैं, आपको निश्चित रूप से पढ़ने में इंटरेस्ट भी आएगा और सब्जेक्ट में पकड़ भी मजबूत होगी।   

You can understand Physics from our channel, you will definitely get interest in studying it and your grip on the subject will also become stronger.

Technical Physics lectures by Dr. Ashutosh Pandey cover 

Relativistic Mechanics

The branch of physics known as relativistic mechanics spends learning the motion of objects travelling at speeds that are very close to the speed of light. It is based on Einstein's special relativity theory. In relation to relativistic mechanics, terms like time dilation, length contraction, Lorentz transformation, relativistic momentum, relativistic energy, and E=mc2 are often searched on Google. The concepts of special relativity are examined throughout the course, along with the impact of motion on space and time and how physical quantities change depending on the frame of reference. Included are practical applications in high-energy physics, mathematical techniques like Lorentz transformations and four-vectors, and the interactions between energy, mass, and momentum in relativistic systems. Further research in the disciplines of general relativity, quantum physics, and related subjects can be built on this information.
