Ek = 1/2 me v^2

Ek = 1/2 me v^2

In this formula for kinetic energy, will me always be 9.109 x 10^-31 kg?

In this case me will always be 9.109 x 10^-31 kg because me is mass of electron. But the mass of other particles can be used in this place e.g. mp or mn for mass of proton or neutron respectively.

In this equation, the mass of an electron will always be 9.109 x 10^-31 kg.
