Asystem consists of two objects that collide in a partially elastic collision. which two properties of the system are conserved by the collision? mass and kinetic energy momentum and mechanical energy momentum and kinetic energy momentum and mass

Mass , momentum and mechanical energy

Explanation:

There are two types of collision.

1. Elastic collision: in case of elastic collision no energy is loss in form of heat and sound .

The momentum and the kinetic energy is conserved.

2. Inelastic collision: in case of inelastic or partially elastic collision, some of energy is lost in form of heat or sound. Here momentum and mechanical energy is conserved.

Mass of a system is always conserved.

i think they are all correct

explanation:

they seem good
