instantaneous, inelastic, elastic, pulse or impulse?

Response Details:
impulse.  When something strikes something else, for a split second it gives out an impulse, which in turn gives both objects momentum or both objects lose momentum, etc.
Don't just read this response and expect to understand everything.  Grab a pen and paper and work it out as you go along, it'll make your life much easier.

Impulse: The magnitude of the force mulitiplied by the time in which it acts, also defined as the change in momentum. This can be a measure of the damage that is applied to a particular body in a collision
 
hope this helps

Response Details:
The impulse of the force F acting on a particle equals the change in the momentum of the particle. The single force F acts on a particle and that this force may vary with time. dp=Fdt
 
The answer is IMPULSE.
