How much should you increase the mass in spring oscillator to double its period? ....... increase 2-times ....... increase 4-times ....... decrease 2-times An object that has a small mass and an object that has a large mass have the same momentum. Which object has the most kinetic energy? ....... object with small mass ....... object with large mass ....... both objects will have a same kinetic energy Which rolls down an inclined plane faster, a solid cylinder or a solid sphere? Both have the same mass and radius. The moment of inertia for a sphere and cylinder equals l=2mR215 and l=mR212, respectively
