Question about units in De Brogiles Equation and the Heinsberg Uncertainty Equation

[Carina H - 2G]

Hi!

Just double checking, when calculating momentum in both de brogiles and heinsberg uncertainty equations, the mass must be in kilograms, right? Or do we just leave mass as grams? I know that for the kinetic energy = .5(m)(v^2), mass is in kilograms so I wanted to check for the other equations. Thanks!

Yes, both are in kg!

[Eric Sun 2G]

Kg is the units for this type of problem.

The unit for mass should be in kg.

[Joan Moci 1J]

Since in both those equations you are dealing with momentum which units are kg*m/s, the mass must therefore be in kilograms.

[Jennifer Fuentes 2K]

hi yes it will be kg because you're dealing with momentum which your mass will end up having to be converted into kg

[daniellediem1k]

Yes mass is in kg!

[Kailin Mimaki 2K]

When calculating momentum, use kg for the units for mass and m/s for velocity and you should be all set to solve the problem. Hope this helped!
