Answer:
See the answer below
Step-by-step explanation:
The aspect of the event that relates to matter is the materials and different shapes of the balls while the aspect that relates to energy is the heights reached by the balls as they bounce off the same floor.
Matter is generally defined as any substance that has weight and is able to occupy space. Hence, the balls being made up of different materials and shapes means that they are made up of matter.
Energy, however, is generally defined as the capacity to do work. The more the energy of a system, the more the work that can be done by the system. The height reached by the balls is thus an indication of the amount of energy possessed by the balls.
