Momentum is defined as mass times velocity, and it requires units of mass times units of velocity. The SI unit is kilograms x meters / second. There is no special name for this combination of units.
Impulse (force times time) has the same units.

What mass of sodium chloride contains 4.59 exp24 formula units?
The gram formula unit mass of sodium chloride is 58.443, and every gram formula unit mass contains Avogadro's Number, 6.022 X 1023 formula units. Therefore, the mass sought is 58.443 X (4.59 X 1024)/(6.022 X 1023) or 445 grams, to the justified number of significant digits.
How much is mass?
This is determined by Einstein's equation E = mc2, where c = velocity of light = 3 x 108 meters/sec. So c2 = 9 x 1016. For 1 kg of mass therefore the equivalent energy is 9 x 1016 Joules, for 1 gram it is 9 x 1013 Joules.Note units, in the SI system energy is in Joules, mass in kg, distances in meters. If you keep to these units you will get consistent results.The above of course only holds for the complete annihilation of 1 gram or 1 kilogram of mass, which does not happen in chemical reactions, so don't try to apply it in such cases!
If crystal salt has a mass of 0.12 g how many NaCl formula units does it have?
1.24 x 10 (18th) molecules .12mg x 1g/1000mg x 1mol/58.443g (molar mass of NaCl) x 6.022 x 10(23rd) molecules/1mol =1.236 x 10 918) molecules :) hope this helps! -forensics major currenly!!
Calculate the mass in grams of 2.5 moles in calcium carbonate?
For this you need the atomic (molecular) mass of CaCO3. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel. CaCO3= 100.1 grams2.50 moles CaCO3 × (100.1 grams) = 250.25 grams CaCO3
Calculate the mass of 0139 moles of copper?
Mass = moles x formula mass Mass = 0.139 x atomic mass of copper (63.5) Mass = 8.83g
What are the units you use for measuring a moment?
If you mean a brief moment of time: seconds.If you mean momentum: this is mass x velocity, so the units are kg x meters / secondsIf you mean a brief moment of time: seconds.If you mean momentum: this is mass x velocity, so the units are kg x meters / secondsIf you mean a brief moment of time: seconds.If you mean momentum: this is mass x velocity, so the units are kg x meters / secondsIf you mean a brief moment of time: seconds.If you mean momentum: this is mass x velocity, so the units are kg x meters / seconds
Is momentum the same as force yes or no?
It is not, and it doesn't even have the same units. Momentum has the units of force x time (or equivalently, mass x velocity).
M omentum is expressed in units of?
Momentum is defined as mass times velocity, and it requires units of mass times units of velocity. The SI unit is kilograms x meters / second. There is no special name for this combination of units.
What is the units for moments?
Since moment is mass x velocity, you need corresponding units. For example, in the SI, kg x meters / second.
What are the units of momentum called?
Momentum is the product of mass times velocity, so in SI units, the units are kilograms x meters / second. There is no special name for this unit.
The impulse given to a ball with mass of 4 kg is 16 Nsec If the ball starts from rest what is its final velocity?
An impulse is simply a change of momentum, and momentum is defined as mass x velocity; so you just divide the momentum by the mass to get the velocity. Note about the units: newton x second is the same as kilogram x meter/second2.
How many Kilogram are in 1.27 x the exponent of 4?
None. A kilogram is a measure of mass. The 1.27 x etc is a pure number and has no units of mass associated with it.
What unit of measurement determines how hard it is to stop an object?
That may refer to an object's mass (units: kilograms), to its momentum (measured in mass x velocity, units are kilogram x meter / second), or to its kinetic energy (measured in joules).
What is momentum divided by velocity?
Momentum = mass x velocity. If you divide out the velocity you get mass.
What are Units of particle motions?
"Motion" can be expressed in units of speed. Or it might refer to momentum - in which case you would use any unit of mass x velocity.
What is the formula to calculate kinetic energy?
Kenetic energy equals one half mass times velocity squared.
What does momentum of an object mean?
Momentum is the product of mass x velocity.
