When two object is move in opposite direction one will have positive and other have negative momentum why?
Momentum is defined as a vector quantity; this means that the direction matters. Only if it is defined as a vector quantity do you have something called "conservation of momentum", which makes it very interesting for physics.
Do all objects have a momentum?
No. An object has momentum only if it is in motion..There are two kinds of momentum: linear momentum(or translational momentum), and angular momentum (or rotational momentum)..Linear momentum is a vector quantity and is calculated as mass x velocity (p = mv). Therefore, if an object's velocity is zero, then it has no linear momentum, but if an object is in motion, then it does have linear momentum..VERY IMPORTANT NOTE: Velocity, and therefore linear momentum, is always relative to the frame of reference. For a more complete discussion about velocity, see the related answer, referenced below, entitled 'How to Find Velocity'..Angular momentum is a pseudovector quantity that describes the momentum of an object that is spinning or rotating in place. An object has angular momentum only when it is spinning, or rotating about an axis. When an object is not spinning or rotating, then it does not have angular momentum..It is possible for an object to have only linear momentum, only angular momentum, or both angular and linear momentum. Note that this discussion falls apart in quantum mechanics, so we are only discussing classical physics - that is, every day observable objects, and not light particles (photons), electrons, or other quantum particles..All objects do have inertia, which is a resistance to a change in its momentum.
What is the product of an object's mass and its velocity?
The product of an object's mass and its velocity is called its momentum. Sometimes it is also called linear momentum, to distinguish it from angular momentum - however, when the word "momentum" is used alone, it usually refers to linear momentum.
What is physical significance of linear momentum?
The same as momentum - sometimes called "linear momentum" to distinguish it from angular momentum. Linear momentum is the product of mass times velocity. It is a conserved quantity, making it very useful for certain calculations.
How is speed related to momentum?
Speed and momentum are related because momentum is the product of an object's mass and its velocity. In other words, momentum is directly proportional to an object's speed. This means that as an object's speed increases, its momentum also increases.
Explain why the stress is considered as a tensor quantity?
If the surface area is very very small then stress is a Tensor quantity.... -MOGRE

Is Rural Tourism a new alternative of tourism category?
It is an alterantive in relation price-quality. In Spain is very important. It contribute to the PIB in a very important quantity.

Why is Garnet considered important in the study of rocks?
Garnet is considered important in the study of rocks because of its molecular composure. Garnet has a very weak molecular composure, making it a very maleable rock.
What was considered as important as religion?
The ancient Greeks believed that religion was very important. The arts were very important to them as well. Music and architecture was very important to them as well. For them, all of these were extremely important, and each one was thought to be equally important and necessary.
Speed plus direction is what?
Speed is a measure of how fast an object is going. This is a scalar quantity, which means it only gives magnitude (size) information. Velocity is a vector quantity, which is very similar to speed, but it also includes direction information.Example:Speed of car = 60 km/hVelocity of car = 60 km/h in a Northwesterly direction
Rocket works on the principle of conservation of?
linear momentum. A rocket works by expelling gases from one end at a very high velocity. The escaping gases have a very high speed and this with their mass translates to a very large momentum. Due to the principle of conservation of momentum the body of the rocket is pushed forward. If both the momentum of the gases as well as that of the rocket are added the sum is zero.
Can an elephant have the same momentum has a golf ball?
Momentum, in classical terms, is defined as mass x velocity. So, theoretically, an elephant could have the same momentum as a golf ball if the golf ball (small mass) is moving very, very fast, and the elephant (large mass) is moving very, very slowly. If the product of the mass x velocity is the same, then the momentum can be the same.
