INTRODUCTION: WHAT IS DYNAMICS? Dynamics is the part of mechanics that studies how forces affect the motion of objects. While kinematics describes how things move (displacement, velocity, acceleration), dynamics explains why they move that way. For CBSE, JEE, NEET and other exams, dynamics is built mainly on: Newton’s Laws of Motion Work–Energy Theorem Conservation of Momentum Circular Motion, and sometimes springs, pulleys, etc. Circular Motion, and sometimes springs, pulleys, etc. Circular Motion, and sometimes springs, pulleys, etc. Below you’ll find: Fundamental laws of physics involved in dynamics (with MathJax delimiters) Ten problems, from simple to challenging, with full solutions and the key laws stated for each.

Inserting an insulating material between its plates drastically changes the capacitance, stored energy, and potential difference of a capacitor with a dielectric under varying conditions. Consequently, the SEO key phrase "Capacitors with dielectrics change energy and voltage" effectively captures both the underlying physics principle and its real-world implications. This topic forms one of the most fundamental problems in electrostatics because capacitors with dielectrics change energy and voltage depending on whether the battery remains connected or is removed. Specifically, they achieve this by modifying the electric field distribution, a crucial understanding for students preparing for physics exams and for engineers designing modern circuits. In this detailed article, we will not only solve a classic problem involving a capacitor with a dielectric […] READ MORE...

Rutherford atomic model explains the nuclear structure of the atom with a bold claim: nearly all mass and positive charge reside in an extremely small nucleus while electrons occupy the surrounding space. Proposed after the famous gold-foil experiment, Rutherford atomic model explains the nuclear structure of the atom by overturning the “plum pudding” picture and introducing a concentrated center capable of deflecting energetic alpha particles. In this article, we retrace the experiment, derive the scattering law, compare models, and show why this was a foundational leap toward modern quantum physics. From experimental setup and data reduction to MathJax-powered derivations of the Rutherford differential cross-section, the narrative keeps returning to one theme: Rutherford atomic model explains the nuclear structure of the […] READ MORE...
