- Tearing paper
- Ice melting
- dissolving
Chemical Change:
- Something rusting
- photosynthesis
- metabolism/digestion
- Nuclear power [atoms are arranged differently]
- Smashing paper with two metal balls, burns paper
- Electricity in water, breaks H2O into H2 and O2

Answer:
Mass and density in the increasing order among the mentioned balls are as follows: golf>rubber>plastic whereas Motion of rubber ball is higher than of golf and plastic ball due to elasticity of the rubber.
Moment of inertia of the ball is dependent on the mass and velocity of the balls which in turn will determine the motion of the balls. Elasticity property of the rubber ball will help to provide opposite force and can enhance the motion of the rubber ball as compared to golf or plastic balls.
