Conservation of Energy during Contact between Ball and Floor
Introduction:
When a rubber ball bounces off the floor, it is in contact with the floor for a fraction of a second. During this contact period, various energy transfers and conversions take place. The conservation of energy principle can help us understand these phenomena.
Conservation of Energy:
The law of conservation of energy states that energy cannot be created or destroyed; it can only be transferred or converted from one form to another. This principle holds true for all interactions and processes in the universe.
Energy Transfers and Conversions during Ball-Floor Contact:
During the contact between the ball and the floor, several energy transfers and conversions occur, which can be explained using the conservation of energy principle.
Kinetic Energy Conversion:
As the ball hits the floor, its kinetic energy decreases. This energy is transferred to the floor in the form of vibrations and heat. However, the conservation of energy principle ensures that the total energy remains constant.
Potential Energy Conversion:
When the ball compresses upon hitting the floor, its kinetic energy is converted into potential energy due to deformation. The ball stores this potential energy as elastic potential energy, which is then released as the ball rebounds.
Conservation of Energy Validity:
During the entire contact period, the conservation of energy principle remains valid. Although the ball's kinetic energy decreases and is converted into potential energy, the total energy of the system (ball + floor) remains constant.
Explanation of Correct Answer:
The correct answer is option 'D' - both statements B and C are correct.
- Statement B: Conservation of energy is valid during this period. This statement is true because energy is neither created nor destroyed during the ball-floor contact. The energy transfers and conversions obey the conservation of energy principle.
- Statement C: As the ball compresses, kinetic energy is converted into compressed potential energy. This statement is also true. The deformation of the ball stores energy in the form of potential energy, which is later released as the ball rebounds.
Conclusion:
During the contact between a rubber ball and the floor, the conservation of energy principle holds true. The ball's kinetic energy is converted into potential energy due to compression, and the total energy of the system remains constant.
