Physics – 1.7.1 Energy | e-Consult

The ball possesses gravitational potential energy (GPE) at 2m, which is converted into kinetic energy (KE) as it falls. Upon hitting the floor, the KE is converted into other forms of energy such as sound, heat, and deformation of the ball and floor. The total energy of the system (ball + floor) remains constant due to the conservation of energy. Therefore, the ball does not sink into the floor because the energy is dissipated into various forms rather than being absorbed by the floor.

• Gravitational Potential Energy (GPE) is converted to Kinetic Energy (KE).
• Upon impact, KE is dissipated into sound, heat, and deformation.
• The total energy remains constant, preventing the ball from sinking.
