The quantities remaining constant in a collision are
The quantities remaining constant in a collision are
Momentum, kinetic energy and temperature
Momentum and kinetic energy but not temperature
Momentum and temperature but not kinetic energy
Momentum but neither kinetic energy nor temperature
The quantities remaining constant in a collision are
since velocities of the colliding bodies change, the $K.E.$ will change. The shapes of the bodies at the time of collision change due to the force, hence temperature will also change.
Only the momentum will remain constant.
