What happens to bulk of potential energy of a glass that falls from a table and breaks
Correct answer: D. Consumed in breaking of glass
- A. Converted into kinetic energy
- B. Wasted in air
- C. Converted into sound
- D. Consumed in breaking of glass
Explanation
Energy Transformation: The potential energy of the glass is indeed initially converted to kinetic energy as it falls. However, the breaking of the glass itself requires energy. This energy comes from the kinetic energy the glass gained during its fall.Energy Dissipation: The breaking process involves overcoming the forces holding the glass together. This energy is not "wasted" but is used to create new surfaces, generate heat, and produce sound

About Work and Energy
Work transfers energy when a force causes displacement, while kinetic energy, gravitational potential energy and power describe motion, position and the rate of energy transfer. The work-energy theorem links net work with change in kinetic energy, and efficiency accounts for energy losses rather than treating them as energy destruction.
