the SI unit of momentum is :- kg.ms-1
and we know that,
kinetic energy = 1/2 mv2
E=p2/2m
p=(2Em)1/2
so the derived units are (J.kg)1/2

Which is the SI unit of momentum?
Momentum = mass x velocity, so logically, the unit is kg x meter / second. This unit has no special name.
What is si base unit for momentum?
The SI unit of Momentum is kilogram meters per second --> (kg*m)/s
What is the base unit of mass?
The mass is obviously a base unit. From mass we can derive many units like momentum, force etc. But we cannot derive the unit of mass from any other unit. So, it's a base unit. Technically, mass is not a unit. In the most commonly used systems of units, MKS and cgs, units of mass (kilograms and grams, respectively), are base units.
How would you distinguish a fundamental unit form a derived unit?
a fundamental unit is fixed in unlike a derived unit which is varying
Why does momentum have no designated SI unit name?
It does. Momentum=mass* velocity. Momentum is kilogram meters per second
What is the unit of linear momentum?
(Any unit of mass) times (any unit of speed) is a unit of linear momentum. Angular momentum would need radians.In the SI (metric) system, it's kilogram meter per second kg.m.s-1 or Newton-second.
Is volt a metric unit?
Yes, it is part of the SI. It is a derived unit.Yes, it is part of the SI. It is a derived unit.Yes, it is part of the SI. It is a derived unit.Yes, it is part of the SI. It is a derived unit.
Why do you need momentum with kinetic energy?
Momentum is the product of mass and velocity. Kinetic Energy is the product of mass and velocity squared. As you can see, since Kinetic Energy is derived from mass and velocity, and Momentum is derived from mass and velocity, you cannot have one without the other.
Is the unit for density a derived unit?
no
What is the unit of impulse in physics?
Same as the unit of momentum - an impulse is a transfer of momentum. Velocity x mass. Or the equivalent force x time.
Is the cubic centimeter a base or derived unit?
yes, cubic centimeter is a derived unit.
Why is the momentum of a bullet equal to that of a gun?
In the recoil? This follows from conservation of momentum. Actually, the momentum of the gun will be exactly opposite - or the negative - of the bullet's momentum. It can also be derived from Newton's Second and Third Laws.
