Physics - Work Power Energy
Practise 14 KCET previous year questions on Work Power Energy, compiled from papers spanning 2009 to 2025. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty KCET tests.
Work Power Energy has been asked in 12 of the 20 years of KCET papers analysed (2007–2026), with 14 questions in all. 29% of them were easy, 50% moderate and 21% tough. Most of its questions came from 2024, with 2 questions that year. In the last three years (2024–2026) it had 3 questions across 3 papers, about 1 per paper.
The chapter's 4 topics are not weighted equally: Energy (7 questions, 50%), Work done (4 questions, 29%), and Power (2 questions, 14%) have been asked the most. Energy has also led over the last five years, with 2 questions. Work done has produced the most tough questions (2).
