What is the conversion factor between kg/m^3 and g/m^3. express your experimental values for the densities in kg/m^3.

Is it possible to use the energy from two atoms colliding to create a clean burning lasting fuel source with a large amount of force? is it also possible to harness that energy from the two atoms colliding to create a clean energy source that will last for years from just two atoms colliding. is there a possibility to control and store that energy for years but slowly let the energy out enough to power cities cheaper and faster.

Often called simply "velocity," this is the velocity of an object at a particular moment in time.
