NEET 2025:The kinetic energies of two similar cars A and B are 100 J and 225 J respectively. On ap

For NEET Physics preparation, focus on NCERT textbooks first, then move to reference books. Create a topic-wise study plan covering Mechanics, Thermodynamics, Electromagnetism, Optics, and Modern Physics. Solve previous years’ questions and take regular mock tests. Pay special attention to conceptual clarity and numerical problem-solving skills.

In elastic collisions, both momentum and kinetic energy are conserved. Examples include collisions between hard billiard balls. In inelastic collisions, only momentum is conserved while some kinetic energy is converted to other forms like heat or sound. Most real-world collisions are inelastic to some degree.

To solve physics numerical problems effectively, first understand the concept thoroughly. Then follow these steps: 1) Read the problem carefully and identify the given quantities and what needs to be found. 2) Draw a diagram if applicable. 3) Write down the relevant formulas. 4) Substitute the values with proper units. 5) Solve step by step. 6) Verify your answer by checking units and whether the result makes physical sense.
