Comparison Problems in Physics

Comparison Problems in Physics

Comparison Problems are Numericals in Physics, wherein a concept in the form of an equation will be applied for two sets of values for the variables given in the equation. The outcome needs to be determined by solving those equations either by simple division / algebraic methods. 

Logical reasoning problems in physics

Logical Reasoning Problems

Problems involving Logical Reasoning are common in Physics. Students make mistakes in such problems by not reasoning the concepts correctly. Such problems are discussed in the below videos.

One problem a Day

One Problem a Day / HW Portal

Solving one problem daily can sharpen problem-solving skills, build a steady learning rhythm, and lead to a deeper understanding of each concept over time. It also allows room for focused analysis and critical reflection, making this a sustainable approach for long-term improvement.

Conceptwise questions

Concept Wise questions for each unit

concept-wise questions helps you focus on one key idea at a time, making it easier to understand and remember. By practicing these questions, you’ll get a solid grasp of each concept, which makes solving complex problems simpler.
