What If? Physicists often measure the momentum of subatomic particles moving near the speed of light in units of MeV/c, where c is the speed of light, and 1 MeV = 1.6 ✕ 10−13 kg · m2/s2. Based on this, what are the units of momentum for a high-speed subatomic particle in terms of fundamental SI units?

The unit of momentum is the product of the units of mass and velocity. In SI units, if the mass is in kilograms and the velocity is in meters per second then the momentum is in kilogram meters per second (kg⋅m/s)

This question is dealing with fundamental SI units. Thus, let's list the seven basic SI Units upon which other units are expressed;

Mass - kilogram (kg)

Length - meter (m)

Time - second (s)

Amount of substance - mole (mol)

Electric current - ampere (A)

Thermodynamic temperature - kelvin (K)

Luminous intensity - candela (cd)

Fundamental SI unit of momentum is Kg.m/s

Now, we want to write the SI Unit of momentum.

From the question, we are told that Physicists often measure the momentum of subatomic particles using the formula;

MeV/c, where c is the speed of light, and 1 MeV = 1.6 ✕ 10−13 kg.m²/s²

Now, we know that unit of speed is in m/s.

Thus, in units, momentum = MeV/c = (kg.m²/s²)/(m/s)

Simplifying this gives; Kg.m/s
