Answer:
Explanation:
If no Energy is lost ( either as Sound energy or any other energy) the total energy of ball A equals the total energy of ball B
Therefore the Kinetic Energy of Ball B equals the Total Energy of Ball A minus the Potential Energy of Ball A
K. E = T. E - P.E
Answer:
It is neither false nor true. When they collide some of one of the objects goes to the other object.
