Frequently Asked Questions

What are the dimensions of momentum and energy?

The dimensions of momentum units are T−1LM. The dimensions of energy units are T−2L2M. Then, dividing the units of energy (such as eV) by a fundamental constant that has units of velocity ( T−1L ), facilitates the required conversion of using energy units to describe momentum.

How many eV in 1 joule?

1 joule is equal to 6.2415064799632E+18 eV. Valid units must be of the energy type. In physics, the electron volt (eV) is a unit of energy. By definition, it is equal to the amount of kinetic energy gained by a single unbound electron when it accelerates through an electrostatic potential difference of one volt.

How to express mass and momentum in terms of electron volts?

compared to the non-relativistic result p = mv = x10^kg m/s which would then be in error by %. In the above calculations, one of the ways of expressing mass and momentum is in terms of electron volts.

What is the SI unit of momentum?

Mass is measured in kg and velocity in ms -1, therefore, the SI unit of momentum will be kgm/s (-1). If we consider the situation when force is equivalent to the rate of change of momentum: i.e. Force= (change in momentum)/ (time interval) then, change in momentum = Force * (time interval).
