Different types of moments of inertia can be better suited to different purposes and situations. If you wanted to store power in a spinning object, you could store more power in an object with a …

Closely related to momentum is impulse (denoted by J), which is simply the initial momentum subtracted from the final momentum. The idea of impulse is important in things like mechanical engineering …

In motion problems you can use the truth, but you can also sometimes use the principle of conservation of energy, and it is often simpler. In a closed system, energy will not be created or destroyed, …

The less wise of a group of monks, after hearing the equation x-x0=v0xt and rushing away from the physics lecture, thought that if they gave building blocks a simple push they would continue moving …

Richard Feynman pioneered the field of Quantum Electrodynamics and won the Nobel Prize in physics. He went to school at MIT and Princeton and went on to later teach at Caltech. Feynman also traveled …
