calculating kinetic energy

Postby Vikramjeet Gill 1C » Mon Oct 08, 2018 1:19 pm

For the equation Ek=1/2(M)(V^2)
M stands for the mass of the electron, is the unit for that mass suppose to be in grams or kilograms for this equation?

The standard units are kg, so I think your mass should be in kg. The mass of an electron is 9.11x10^-31 kg; so I think that is the number that should be used in the equation.

Mass will be in kg, because that is the standard SI unit!

That should be kg. We use SI units in all equations.

The unit is supposed to be in kg, as that is the standard SI unit.

We would use kg in the equation because it is the standard SI unit. Most equations will use base SI units.
