This video shows how to apply the work–energy principle to real physical systems beyond ideal point particles. Learn how external work, internal forces, and energy losses are handled in practical ...

Solving Problem 1 on work and energy from an old physics final exam. Follow the step-by-step reasoning behind classic work–energy principles and see how foundational physics problems were approached ...

IBM's quantum computing roadmap leads to the development of quantum processors with thousands of qubits by 2025. Like the early developers of conventional computing methods back in the 1940s, today’s ...

For decades scientists have been trying to solve Feynman's Sprinkler Problem: How does a sprinkler running in reverse—in which the water flows into the device rather than out of it—work? Through a ...

For decades scientists have been trying to solve Feynman's Sprinkler Problem: How does a sprinkler running in reverse work? Through a series of experiments, a team of mathematicians has figured out ...
