List of unsolved problems in physics Some of the major unsolved problems in physics are theoretical, meaning that existing theories seem incapable of explaining a certain observed phenomenon or experimental result The others are experimental, meaning that there is a difficulty in creating an experiment to test a proposed theory or investigate a phenomenon in greater detail. Five Great Problems in Theoretical Physics ThoughtCo Unsolved Problems in Physics According to Lee Smolin The problem of quantum gravity Combine general relativity and quantum theory into a single theory that can claim to be the complete theory of nature The foundational problems of quantum mechanics Resolve the problems in the foundations of quantum mechanics, Physics Problems with Solutions and Tutorials Physics problems with solutions and tutorials with full explanations are included More emphasis on the topics of physics included in the SAT physics subject with hundreds of problems with detailed solutions Physics concepts are clearly discussed and highlighted. Example Physics Problems and Solutions Science Notes and Learning how to solve physics problems is a big part of learning physics Here s a collection of example physics problems and solutions to help you tackle problems sets and understand concepts and how to work with formulas Physics Homework Tips Physics homework can be challenging Get tips to help make the task a little easier. Solving Problems in Physics University Physics Volume Problem solving skills are clearly essential to success in a quantitative course in physics More important, the ability to apply broad physical principles usually represented by equations to specific situations is a very powerful form of knowledge It is much powerful than memorizing a list of facts. Sample Problems and Solutions Physics Sample Problems and Solutions These problems allow any student of physics to test their understanding of the use of the four kinematic equations to solve problems involving the one dimensional motion of objects You are encouraged to read each problem and practice the use of the strategy in the solution of the problem.
