two identical cars have the same speed,one travelling east and the other west.do they have the same momentum?

Answer 1

They have the same amount of momentum.

However since momentum, strictly speaking, is a vector, their momentums are not directed in the same direction. Meaning they do not have the same momentum. They do have the same amount.

Answer 2

As others have noted, the direction matters. Otherwise the momentum is the same. Wind speed etc. don't matter, you said the speed was the same and the cars identical so the size of the momentum is the same.

But I suppose reason you ask is that you wonder if it matters that the one travelling East travels in the same direction as Earth's rotation while the one traveling West doesn't. So relative to someone who doesn't follow Earth's rotation, the one travelling East has the largest momentum since it's p0+p, where p0 is the momentum it would have if it where at rest only carried by Earth's rotation, while the onle traveling West has a momentum of p0-p.

But everything is relative, you can measure velocity (and therefore, momentum) relative to whateever frame of reference you want, and that of a car is usually measured relative to the surface of the Earth. So I would say that the size of the momemtum is the same for both cars.

Answer 3

No they do not have the same momentum.

Momentum is a vector, which means that it is dependant on direction. Thus, in a standard x-y coordinate system, the one travelling east would have positive momentum and the one travelling west would have negative momentum.

The MAGNITUDE of the momentum will, however, be the same.

Answer 4

At one seem of the question, you are able to tell that the momentum of the two autos are distinctive. The very reason that's so is with the help of the valuables of Momentum, which describes it as a vector. Momentum(vector) = Mass(scalar) * velocity(vector) because in momentum we expect relating to the cost of the physique, then we could additionally think relating to the direction of the action of the physique. subsequently, the two autos are traveling in distinctive instructions, so they needless to say have distinctive momentum, as considered under: Momentum of motor vehicle one million = M * V since the different motor vehicle is traveling interior the different direction, its velocity would be detrimental: Momentum of motor vehicle 2 = M * -V as a result, we are able to confirm that MV is easily no longer equivalent to -MV. despite the fact that if we assume that the mass of the two autos are equivalent, their momentum will nonetheless be distinctive. inspite of the undeniable fact that, the importance of their momentum stands out as the comparable if their mass are the comparable. The modulus of the momentum of the two autos stands out as the comparable: because their mass are the comparable, enable their mass be M, V1 and V2 be their velocity respectively: |M*V1| = |M*V2| Divide the two facets by applying M: |V1| = |V2| because of the fact the importance of velocity is the cost, velocity of motor vehicle one million = velocity of motor vehicle 2 that's genuine. subsequently, back to the element, the two autos might have distinctive momentum however the importance of their momentum stands out as the comparable on condition that their mass are equivalent. wish this enables. =)

Answer 5

No, one is accellerating relative to the earth's rotation, the other decellerating. The Car Travelling East has a greater momentum.

Answer 6

Not at all there are factors affecting momentum like wind direction & velocity, or if one is travelling on a different plane condition.

Answer 7

Depends if they are both traveling on a level road or if one is going uphill and the other downhill. It also depends on the weight of the passengers and luggage in the car.

Answer 8

nope. momentum is a vector.

direction matters

Answer 9

polloloco has it right - give him/her the 10 points

Answer 10

yup especially after they meet
