In physics power is the rate at which energy is used or work is done. The average power is the energy divided by the time. more...
In physics work has a very specific definition that is different from the everyday definition. A force must be applied over a distance. more...
Understanding Potential Energy
Potential energy is the energy of position resulting from any conservative force. more...
Geosynchronous Satellite Orbits
Communications satellites often use geosynchronous orbits because they remain stationary above the same location on Earth. more...
Kinetic energy is the energy of motion. The work energy theorem is a powerful problem solving tool. Heat or thermal energy is random kinetic energy. more...
Resonant Orbits and Saturn's Rings
The Voyager space probe to Saturn revealed incredibly detailed unexpected structure in Saturn's rings. Resonant orbits of Saturn's moons help cause this structure. more...
Shepherd Moons & Planetary Rings
The Voyager space probe to Saturn revealed incredibly detailed unexpected structure in Saturn's rings. Shepherd moons help cause this structure. more...

Quantum Leap into Quantum Theory
Quantum mechanics, a spin-off of quantum physics, explores the fabric of reality and our relevance to it through research in science, spirituality, philosophy, and more. more...
Billiards and Angular Momentum
Physics textbooks often use billiards in examples to explain concepts in mechanics - but they teach you very little about how physics can be used in billiards. more...
Centripetal force and centrifugal force are related but often confused. more...
Waves are ubiquitous in the study of physics, and we are intuitively familiar with them from a very early age, but what are they really? more...
Newton's third law states that when one body exerts a force on another body, the second body responds with an equal and opposite force. more...
Newton's Second Law describes the relationship between force, mass, and motion, and is an essential tool used to unravel the mysteries of the mechanical Universe. more...
Newton's First Law, the simplest of Newton's three laws of motion, provides a frame of reference for understanding all motion in the Universe. more...
