What happens when masses collide.?
109475
When masses collide, they exchange energy and momentum.  I'm not sure what you mean specifically by "power division", but you might be referring to this exchange of energy, since power is defined as energy transferred per unit time.  If so, just know that the important thing is that the total amount of energy and momentum is conserved, that is, remains constant.\n\nAddendum-  What the next correspondent says about elastic and inelastic collisions is correct; it makes a difference in how energy is transferred.  In every collision, total energy is conserved, as I said, but in elastic collisions, mechanical energy is conserved as well.  That is, none of the energy is converted to other forms of energy like heat, light or potential energy of deformation.  In inelastic collisions, momentum and total energy are conserved, but some of the mechanical energy is converted to those other forms.

I think the hardest question ever asked was asked by a scientist.  This was the question, and it literally drove him insane thinking about it:  Two large metallic orbs are traveling towards each other on a collision course.  Both are indestructable, and nothing can divert them from their path in any way.  They can never stop moving on their path for any reason.  What would happen when they collide?  Neither can be moved from the path that they are traveling, they cannot be destroyed, and they can never stop moving.

Mass. I think.Depending on how strong the gravity is your mass changes.

Actually the opposite. Conservation of Mass says that Mass can not be created or destroyed, only converted to a new form of mass. The only exception is in nuclear reactions, in which Mass can become Energy and vice versa.

Generally, some of their collective kinetic energy is converted into heat, so the KE after the collision is less than the initial KE.  Momentum is conserved.

mass doesn't change. Only weight changes because weight is mass times the acceleration due to gravity.\n\nWt=mg

good start.\n\ntotal inital momentum = 480-397.5\n\nthis is an inelasitc collision, and aferwards you have \nboth masses travelling at velocity v:\n\n(75+120)v = 480-397.5\n\nsolve for v.  This is the velocity at which they both slide.\nThe inital energy now is 1/2(75+120)v^2\n\nThis energy is converted to frictional energy:\n\ninital kinetic energy = total work of friction = Fr(distance)\n\nFr = uN = u(120+75)g = .3(195)(9.8)\n\nso we have\n\n.3(195)(9.8)(distance slided) = 1/2(195)v^2 \n\nYou know v form above.  So find distance slided.

It happens.    Relax.\n\n_

Take two objects of the same mass moving towards each other (in opposite directions) with the same speed. Let's say one object has momentum of p and the other -p. The total momentum of the system (p-p) is 0. When they collide, they both stop moving and the total momentum of the system is still 0.

the gravitational force can act in any medium as well as in vacuum. the sun exerts a gravitational force on the earth across a vast expanse of vacuum! this itself is proof enough.\nthe objects will all touch the ground at the same time whether in a medium or in vacuum. this occurs for the sole reason tht all of them are of equal mass.

Nothin would happen.\nIf you consider two bodies the earth (name it E) and a large mass (m). \ninitially M rests on E. and you lift mass M. the force used to lift it will also act on E.\nAlso if you consider the mass M and E. as a system force exerted on dropping M would be internal and since internal forces do not cause acc. the Earth will not get unbalanced.\n\nThats good for us isn't it...

As far as we can tell, space is infinitely big.  It's rare for galaxies to collide.  It does happen, however.  Below is a link to an article about a recently seen collision.  Keep in mind, however, that because of the distances involved these galaxies actually collided millions of years ago, and the light is just reaching us now.

No energy source? What source of energy is needed? And the simple presence of mass causes gravitons. And these gravitons interact with one another. And proof, you need proof that gravity works? Dude go jump off of a building and see what happens!

First, there is no way they can fall. Falling of things on earth is due to its gravity. Most of the heavenly bodies out there are much much bigger than earth itself (stars, planest like jupiter, neptune, saturn) and they are very far off. \n\nSo if at all you mean to say they collide, it will be like one gigantic explosion and earth will be ripped to pieces (even if something as small as our moon falls!) \n\nThere is no question of where they will fall. The collision point can be any place depending on where the earth is and considering its rotation.\n\n:)

Very simple. start out asking yourself what information do i know about the problem. Anything from masses and forces to symmetries of the problem. Next Ask yourself what additional information you need to solve the problem, values, formulas, etc. from there it should all fall out with ease.
