Which one of the following does not have the same units as the others?
Momentum. The other all have units of energy.
Which of the following is true concerning momentum?
equation of linear momentum =mXv so it is not a force since no change of velocity and hence on acceleration it is not a scalar quantity. it is a vector quantity si unit is Nm/s However momentum is always positive impulse is a function of time
Which of the following momentum statements are true?
Which of the following statements are true? Select all correct responses. Choose all that apply. Choose all that apply. The total momentum of an isolated system is constant. The vector sum of forces acting on a particle equals the rate of change of velocity of the particle with respect to time. The total momentum of any system is constant. The total momentum of any number of particles is equal to the vector sum of the momenta of the individual particles. The vector sum of forces acting on a particle equals the rate of change of momentum of the particle with respect to time. The total momentum of any number of particles is equal to the algebraic sum of the momenta of the individual particles.
What is the S.I. unit of momentum?
We had a discussion about this in my introductory physics class. As others have said, since momentum is calculated as Mass*velocity then one answer is kg m/s. However, it would be nice, since momentum is such an important physical quantity, if there was one unit for momentum. This has been done for other quantities. For example, energy is [math]kg*m^2/s^2[/math] [math]= 1Joule[/math], Force is [math]kg*m/s^2 = 1Newton[/math] and pressure is [math]Newton/m^2 = 1Pascal[/math]. These were all named after famous physicists. My professor, Shane Larson, said he'd be ok with us calling the unit of momentum the Larson.
What is the proper units for momentum using dimensional analysis. (Use kg, m, and s as appropriate.)?
Momentum is mass times velocity. The basic unit of mass is the kilogram, and the basic unit for velocity is meters per second, so the proper units for momentum are (kilogram * meters) / second.
What are the units for momentum?
The SI units are kilogram [math]\cdot[/math] meter/second ([math]kg \cdot \frac {m} {s}[/math]).Momentum - WikipediaImage courtesy Formula For Momentum - justsingit.com
What is the SI unit of momentum? How is it used?
Momentum is defined as the product of force and mass. Therefore momentum p is given by: p=mv So the units of momentum will be the product of the units of mass and velocity. In SI units, when mass is in kg and velocity in ms^(-1), the units of momentum are: kgms^(-1) Using the definition that force is equal to the rate of change of momentum: Force=(change in momentum)/(time interval) Therefore, Change in momentum = Force * (time interval) Here you can see that an alternative unit for momentum is the Newton-second, Ns.
Which one of the following pairs of units may not be added together?
Which one of the following pairs of units may not be added together, even after the appropriate unit conversions have been made? a. grams and milligrams b. slugs and kilograms c. miles and kilometers d. centimeters and yards e. kilograms and kilometers
How can light possess momentum if it has no mass?
Yes. Photons do have momentum.You may be familiar with E=mc^2. But this is incomplete.E^2= (mc^2)^2 + (pc)^2Where m is the rest mass of the object in question.P is it's momentum. And c well is the speed of light in vacuum.Since photons have zero rest mass(fact). We can directly use the relation:-E=pc=> p=(E/c)Since for a photonE=hV =(hc/∆)Where V is the frequency of the wave and∆ it's wavelength.h is planks constant.From this we can clearly infer that photons have a momentum but no rest mass.Also, if you have confusion between why light is attracted to black hole even though it has no mass that is because Gravity just cannot different between Energy (photons) and mass.So in truth, Energy is actually mass and vice versa.
