- 4. energy - the internal energy present in a system due to the kinetic energy of its particles; relates to temperature.
- 5. of Energy - a fundamental principle stating that energy cannot be created or destroyed, only transformed from one form to another.
- 6. energy - the energy of electromagnetic waves, including visible light, which can travel through a vacuum.
- 7. level - the scale at which quantum mechanics operates, focusing on the behavior of particles at the atomic and subatomic levels.
- 9. - the transfer of thermal energy through direct contact between materials.
- 10. equivalence - the principle that mass and energy are interchangeable, represented by the equation
- 11. - the SI unit of energy, defined as the work done when a force of one newton displaces an object by one meter.
- 13. energy - the potential of a chemical substance to undergo a transformation through a chemical reaction, releasing energy.
Down
- 1. - the transfer of thermal energy in fluids (liquids and gases) through the movement of the fluid itself.
- 2. potential energy - the energy an object possesses due to its position in a gravitational field, calculated as PE=mgh.
- 3. energy - the energy of an object in motion, depending on its mass and velocity.
- 8. - the capacity to do work or produce change; it exists in various forms (e.g., kinetic, potential).
- 10. potential energy - the energy stored in an object due to its position or configuration, often related to stretching or compressing.
- 12. energy - the energy released during nuclear reactions, such as fission or fusion, typically found in the nucleus of atoms.
