Interpretation: From the given figure, what happens to the energy of Ball A should be determined.
Concept Introduction: Energy is the ability to do work or produce heat. The law of conservation of energy says that the energy cannot be created or destroyed, but it can be converted from one type to another. It is also called the first law of
Answer to Problem 1ALQ
The energy of the ball A in its original position is distributed to ball B as a result of work and to the surface of the hill through heat.
Explanation of Solution
It is given that on reaching the ground, the ball A stopped moving. Considering the law of conservation of energy, the energy must be conserved. The final position gets raised due to transfer of part of energy from ball A to ball B.
The remaining energy of the ball A gets distributed to the surface of the hill in the form of heat as when it moves down the hill, some amount of the kinetic energy gets transferred to the surface of the hill. Thus, the initial energy of ball A gets transferred to the ball B in the form of work and to the hill’s surface in the form of heat.
Therefore, the energy of the ball A in its original position is distributed to ball B as a result of work and to the surface of the hill through heat.
