  2. As a hammer falls, its potential energy decreases while its kinetic energy increases. Upon impact with the nail and wood, the kinetic energy of the hammer is transferred to the nail, causing it to move. This energy transfer drives the nail into the wood, demonstrating the conversion of potential eneRead more

    As a hammer falls, its potential energy decreases while its kinetic energy increases. Upon impact with the nail and wood, the kinetic energy of the hammer is transferred to the nail, causing it to move. This energy transfer drives the nail into the wood, demonstrating the conversion of potential energy into kinetic energy and mechanical work.

  5. In science, energy is defined as the capacity to do work or cause change. It exists in various forms and can be transferred or converted from one form to another, but the total energy within a closed system remains constant (law of conservation of energy).
