The Atwood Machine
Two masses on either side of a pulley with variables of mass and friction. Enter values for the masses of the two balls then hit go to see them fall!
Mass Spectrometer
The mass spectrometer is an instrument which can measure the masses and relative concentrations of atoms and molecules. It makes use of the basic magnetic force on a moving charged particle.
Atwood Machine
The site demonstrate the use of various masses to measure the force exerted on one mass by another.
Explorescience: Driven Harmonic Motion (1 masses)
Apply a driving force to two masses and three springs. Vary masses, spring constants and frequencies & observe different modes of resonance. Part of a great site for teaching advanced physics with ...
Event Horizon
After collapse to the neutron star stage, stars with masses less than 1-3 solar masses should remain neutron stars. Those of masses greater than 1 to 3 collapse toward zero spatial extent - toward a ...
Air Track Simulator
This applet simulates collsions in one dimension. Users can change variables of mass, elasticity and initial speeds of masses on an air track.
Restless Mass
A mathematical site looking at the possible real nature of mass. Asks the question is mass just another form of energy and thus rest mass does not exist. A good site looking at the real nature of ...
Cygnus X-1
Doppler studies of this blue supergiant in Cygnus indicate a period of 5.6 days in orbit around an unseen companion. The mass of the companion is calculated to be 8-10 solar masses, much too large to ...
Chandrasekhar Limit
The calculation of the maximum mass of 1.44 solar masses for a white dwarf was done by Subrahmanyan Chandrasekhar on a ship on the way from India to England to begin graduate study in physics at ...
Reduced Mass
The relative motion of two objects which are acted on by a central force can be described by Newton's Second Law as if they were a single mass with a value called the "reduced mass".
