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.
A good explanation of how a mass spectrometer works
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!
Apply a driving force to two masses and three springs. Vary masses, spring constants and frequencies & observe different modes of resonance. Subscription site but with 30 day free trial.
The site demonstrate the use of various masses to measure the force exerted on one mass by another.
This applet simulates collisions in one dimension. Users can change variables of mass, elasticity and initial speeds of masses on an air track.
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 ...
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 ...
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".
The connection between mass and weight. Links with many other relevant pages such as mechanical quantities and relativistic mass
