If the momentum of an electron is changed, it means that its velocity or mass has been altered. The momentum of an electron is given by the equation:
p = m*v
where p is the momentum, m is the mass, and v is the velocity of the electron.
If the mass of the electron remains constant, then a change in momentum can only occur if the velocity changes. This could happen if the electron is acted upon by an external force, such as in a collision with another particle or due to the presence of an electromagnetic field.
On the other hand, if the velocity of the electron remains constant, then a change in momentum can only occur if the mass changes. However, the mass of an electron is considered to be constant, so this scenario is less likely.
In both cases, a change in momentum implies that there has been a change in the electron's motion, either in terms of its speed or direction.
