... For object sliding on a smooth inclined plane • The acceleration depends on the inclination of the plane only. It does not depend on the mass. Objects of different masses slide on the inclined plane with the same acceleration. • The acceleration always points down-slope, independent of the directio ...

Physics 6010, Fall 2010 Symmetries and Conservation Laws
... By a conservation law we mean a quantity constructed from the coordinates, velocities, accelerations, etc. of the system that does not change as the system evolves in time. When the equations of motion are second order, conservation laws typically arise as functions on the velocity phase (possibly w ...
