newtonian mechanics - Why is there no relation between kinetic energy and momentum in collision of two bodies?



The statement that baffles me:



During most of the collisions, part of the kinetic energy evolve as heat, nevertheless momentum is still conserved.



Ok, the statement may be true. But what confuses me is that: Is there no relation between the momentum and kinetic energy? Are they not linked with each other? Both concerns with velocity. If one decreases, generally it would effect the other. I know something is wrong in my understanding. But I am unable to visualize the above statement. Please help me explaining this.

classical mechanics - Moment of a force about a given axis (Torque) - Scalar or vectorial?

I am studying Statics and saw that: The moment of a force about a given axis (or Torque) is defined by the equation: $M_X = (\vec r \times \...
