What happens to their motional Power, Energy and momentum when Two masses collide?

Question

Collision theory?

Note masses are usually chemical mass structures which can be deformed?

Answer 1

Well, the above answer is correct. That's the fundamental principle of any collision or explosion: since there are no forces external to system and force is the derivative of momentum, then, momentum must be constant, for its derivative equals zero (the sum of all external forces is null). But then, there are two main different kinds of collisons: elastic and inelastic. In an elastic collision, the kinetic energy is maintained and, therefore, it is the same before and after the collision. In an inelastic collison, there is a loss of kinetic energy during the collision, thus altering the kinetic energy of the system. The same may be said considering an explosion.

Answer 2

When two objects collide, the momentum before will equal the momentum after (momentum is conserved).
For example, if object A and B have a total momentum of 10kgm/s east before the collision, the momentum after the collision will be the same. note that the momentum components must be added vectorily.
**Momentum = mass x velocity.**
so if a 10kg cart moving at 1 m/s east and hit a identical stationary cart. if the original cart stops, the stationary cart will then move at the same velocity. (ignoring air resistance and friction)
can't help on the power and energy part, sorry
