Momentum (P) is an object's mass times velocity. There are various forms of energy, such as kinetic (KE) and potential for example. In the case of kinetic energy it is related to momentum in the following formula: KE = (P^2)/2m.

What is necessary condition for the conservation of momentum?
No external forces. Objects may bounce off each other, or merge but the total momentum is unchanged even when the total energy changes.
When two bodies having same momentum collide what will be the result?
There are two possible results. However, they cannot move in the same direction after the collision.Total initial momentum = p - p = 0where p represent the momentum of each object.From the principle of conservation of momentum;Total initial momentum = Total final momentumThus, Total final momentum = 0There are only two possibilities for this:1. Kinetic energy is conserved. (the collision is perfectly elastic)In this case, they would move away from each other with the same magnitude of initial momentum.2. Kinetic energy is not conserved. (the collision is inelastic)In this case, they would either remain at rest or they will move away from each other with a smaller magnitude of initial momentum each had.Note that if both bodies had moved in the same direction, there would be a net momentum in this direction and momentum would not have been conserved. (Momentum is ALWAYS conserved provided there is no external force acting on the system)
How are the movements of energy and nutrients different from each other?
they crazy.
How are potential kinetic energy different from each other?
Difference is that kinetic energy is the energy of motion and potential is stored energy.
Describe what happens to the momentum of two billiard balls that collide?
They have identical momentum before the collision . The total momentum will the the same before and after the collision. When the balls collide they will bounce apart both with same force and so the same momentum as originally - but in opposite directions. This assumes no energy loss in an ideal elastic collision.
Is momentum conserved when two or more objects push away from each other?
Of course it is. Momentum is always conserved.
What the momentum between two identical balls traveling toward each other at thae same speed from opposites direction?
The momentum of one ball will be exactly the opposite of the momentum of the other ball. The total momentum in this case will be zero.
To every action force is there an equal and opposite reaction force that is the law of conservation of momentum?
No, that is Newton's Third Law of Motion. The Law of Conservation of Momentum is that within a contained set of objects, the total momentum never changes. Objects can only transfer energy to each other, they can never really "get rid" of it.
Why do you get photons or other particles in annihilation of subatomic particles?
In annihilation between electron and positron, you should get nothing in your hand. Instead of that you get a pair of photons. The question is that why should you get the pair of photons. So this is not complete annihilation. The answer is simple to this question. When you bring the electron and positron slowly to each other, they will annihilate to each other and will not produce the photons also. But when the particles come with high speed, they carry the energy and have momentum. This energy is converted into photons of different wave length and the electron and positron disappear or get completely annihilated. When you have heavy particles like protons and anti-protons or neutrons and anti-neutrons strike to each other, you get much larger amount of energy that is left. Because they are brought to each other at high speed, they have high momentum and so carry the large amount of energy. This energy is liberated after the annihilation. When enough quantum of energy is there, you have production of electrons, positrons and neutrinos get generated. The rest of the energy is left in the form of photons. When larger molecules of matter and antimatter will collide with each other, you may get smaller molecules of matter and antimatter in your hand.
What will happen to the momentum of a body whose velocity is doubled?
Momentum = mass x velocity. So if the velocity is doubled, momentum will be doubled as they are directly proportional to each other.
What are some examples of 'momentum' in a sentence?
They lost the momentum in their relationship, it is now dull. He lost his momentum for working hard, he was so close. The momentum is conserved when two bumper cars hits each other.
When a soccer ball is kicked the action and reaction forces do not cancel each other out because?
when a soccer ball is kicked, there is a transfer of energy from your leg to the ball. since the ball is elastic, it coverts the kinetic energy from your leg into potential elastic energy in the for of deformation of the ball. the ball then snaps back to its elastic equilibrium converting the energy back to kinetic energy. also, your momentum is being transferred to the ball, giving it a direction since momentum is a vector. due to these conversions of energy and momentum, the ball is sent off your foot in the direction you kicked it with the same speed you kicked it with.
