What happens when two masses collide?

The impact it`s not similar with a nuclear explosion, in fact it`s not a explosion in the real sense. The whole "explosion" is caused by the friction (which produce heat - and a lot, at the speed of a comet or asteroid). If the planet have atmosphere, the friction began from the outer layers of the atmosphere. If not, the crater will be more larger.\nAt the atomic level nothing special happens; the high temperature is created only by friction.\n(I hope this answer is satisfactory . my English may have mistakes)

It depends on how it came to rest. If it had Striked any other ball then its K.E will be transfered to the other. If u were to catch it , then imagine how u will bring your hand towards the ground so as to reduce its impact.Thus its k.E is transferred to you.\n               But if it were to strike the ground then the case is different.From conservation of momentum ,M1V1=M2V2.If M2 be the mass of earth, it is very large when compared to that of the ball. So to satisfy the above condition, V2 should be negligbly small. so we do not face amy impact. Now consider the case of an asteroid or an Hydrogen bomb.We r sure of expriencing the impact.

Both their accelerations will be the same and equal to the acceleration due to gravity, g=9.81 m/s/s...This is coz the only force acting on them is the force due to gravity

In a vacuum, both objects will land at the same time.

Only a limited answer:  For the special case where M = m, there are just 2 collisions.  After the first collision, V = 0 and v = V's initial value.  In the post-reflection collision the opposite exchange occurs.

I think that the gravitational attraction between two bodies is proportional to the product of their masses and inversely proportional to the square of the distance between them.\nF = G * m1*m2/r²

In physics a collision is said to take place \n * When two bodies physically collide against each other or\n * When the path of one body is changed by the influence of the other body.\n \nEXAMPLES :\n  We have several examples for collision\n * Marbles or carom coins colliding with each other\n * Molecules of a gas colliding with one another etc.\n\nThere are two types of collisions.\n1. ELASTIC COLLISION\n2. IN-ELASTIC COLLISION\n\n1. ELASTIC COLLISION:\n   If there is no loss of kinetic energy during a collision, it is said to be elastic collision.\nExample: collision between atomic and nuclear particles are elastic.\n\n2. INELASTIC COLLISION:\n   If there is loss of kinetic energy during a collision it is said to be in-elastic collision.\nExample: If a ball is dropped from a certain height and the ball is unable to rise completely to its original height, then it would mean that the ball has lost some kinetic energy due to collision.\n\nHEAD-ON ELASTIC COLLISION:\n  It is that elastic collision in which the colliding bodies move along the same straight line path before and after collision.

if they are both going at the same speed, then the mass,size of the wheel and other considerations have already been take in account, so they both should arrive at the same time.\nGod bless,\ngabe

E=mc^2  Wow!  This mean that you can transform energy into a mass as it goes at the speed of light squared.  In other words, if you were to take two objects and both collide at the speed of light, what will be left is only energy in a form of light, fire, etc.  Cool!  Other forms of energy are as mechanical energy, electrical energy, light energy, thermal energy, chemical energy etc.

they would fall at the same time unless there is a force acting upon one of the weight...

They mutually anihilate into energy (generally in the form of gamma-rays).  The energy they produce is the based on the sum of thier masses, and Einstein's famous E=mc^2 equation.

Wow, Your question is so simple, but it's answer is researched for many decades now. \n\nAnyway, Any kind of energy (and the force is the mean in which the energy can be detected) requires the carrier, which is, well, material. Material carrier contains some kind of energy, in a certain amount. When the carrier collides with a body, it gives it's energy away to the body. In case of two carriers collision, a certain reaction occurs, and as the result, there is anoter type of energy or the carriers get destroyed, and their energy goes into heat or light. \n\nThe way of calculating an amount of energy that certain carrier contains, is the aplication of Einstein's formula of equality of the mass and the energy. If You are aware of the energy inside some particle, You can foresee it's influence to another particle.\n\nThe only force that is not connected to the appropriate particle is gravity (although there are some speculations about existence of so called "gravitones", as carriers of gravital energy and representers of the gravity force itself). \n\nThat unique force, which is not understood yet, makes Your question very heavy. Scientists from all over the world have been trying for more then 70 years to make the unified force theory, which could be used for calculations of any kind of force, with equaly accurate result. This would be named "The great unified theory of forces". So, let'hope that this theory will be defined soon, and that You will understand the duality force-matter better, by using it.

Mass (according to Einstein) coz mass changes into mass.

We can't use conservation of energy because this is an inelastic collision. Conservation of momentum does hold, so\n\nm1*u1 + m2*u2 = (m1+m2)*v\n\nu2 is zero. So \n\nv = m1*u1/(m1+m2) = .24 kg*u1/2.85 kg = .084*u1\n\nThe projectile's incident kinetic energy \nKEp = (1/2)*m1*u1^2 = 0.12*u1^2 joules\nThe final kinetic energy \nKEf = (1/2)*(m1+m2)*v^2 = 1.42*(.084*u1)^2 = .0100*u1^2 joules.\n\nPercentage = 100%*KEf/KEp

If you disregard air resistance, both land at the same time.\n\nThe Earth's gravitational pull affects everything equally.

Falling objects do not fall at a constant speed, they accelerate (get faster) the longer they fall. In a vacuum (no air resistance) two objects of the same mass (weight) experience the same acceleration. So if they're dropped from the same height, they will hit the ground at the same time. \n\nIn the atmosphere, air resistance will diminish the force of gravity, so two objects of different shape or density would accelerate at different rates because of different air resistance.

The increase of the gravitational energy (m1+m2)gh is the loss of kinetic enery m(v^2)/2.\nThe bullet gets the same speed as the bob.\nUse conservation of momentum.
