Question

Two magnets are placed on a table, and they immediately move to attach to each other. Which statement is correct about the energies in the system? (1 point) Responses The energy stored in the system is converted to kinetic, thermal, and sound energy. The energy stored in the system is converted to kinetic, thermal, and sound energy. The energy stored in the system is converted to thermal and sound energy. The energy stored in the system is converted to thermal and sound energy. The energy stored in the system is converted to kinetic energy. The energy stored in the system is converted to kinetic energy. The energy stored in the system is converted to kinetic and thermal energy.

Answer 1

The correct statement about the energies in the system is: The energy stored in the system is converted to kinetic and thermal energy.

When the magnets are initially separate, they possess potential energy due to their magnetic fields. As they move toward each other and attach, this potential energy is converted into kinetic energy (as they move) and thermal energy (due to friction and the impact of the magnets joining). Therefore, the conversion involves both kinetic and thermal energy.
