Across
- 4. Energy — Potential energy associated with an object’s position in a gravitational field.
- 6. Energy — Energy that travels in waves, including light and other electromagnetic waves.
- 8. — Done when a force acts on an object, causing it to move over a distance.
- 10. Energy — Visible energy that can be seen by the human eye.
- 12. pulley — Pulley that moves with the load and reduces the amount of force needed.
- 13. — Unit used to measure work or energy.
- 14. pulley — Pulley that stays in one place and changes the direction of force.
- 17. pulley — Two or more pulleys working together to lift a load, providing greater mechanical advantage.
- 19. — Unit of measurement for energy in food; the amount of energy needed to raise the temperature of one gram of water by one degree Celsius.
- 22. — The ability to do work or cause change. Everything in the universe has energy. Energy exists in different forms.
- 24. Energy — Sum of kinetic and potential energy; energy of motion and position combined.
- 26. Energy — Energy stored in the nucleus of an atom; released during nuclear reactions like fission or fusion.
- 27. System — System that exchanges energy but not matter.
- 29. and Axle — Uses rotational motion to transfer force and reduce friction; amplifies force or increases distance traveled.
- 30. Energy — Another term for energy associated with moving electric charges.
- 31. — Energy stored because of an object’s height or position in a gravitational field.
Down
- 1. — Devices that make work easier by transferring or transforming energy.
- 2. — Potential energy stored when something is stretched or squeezed.
- 3. Systems — Processes involved in generating, distributing, and using energy to meet societal needs.
- 5. of Conservation of Energy — Energy cannot be created or destroyed, only transformed from one form to another.
- 7. Planes — Flat surface set at an angle that makes it easier to move objects to a higher elevation by reducing the force needed.
- 9. Energy — Energy an object possesses due to its motion. Depends on mass and speed; measured in joules.
- 11. Energy — Stored energy within a system due to its position or configuration; can be converted to other forms of energy.
- 15. Energy — Potential energy stored when an object is stretched or compressed.
- 16. — Energy associated with moving electric charges.
- 17. Energy — Energy stored in the bonds of atoms and molecules; released or absorbed during chemical reactions.
- 18. — Simple machines that make it easier to lift or move heavy objects by redirecting force.
- 20. Energy — Energy carried by vibrations we can hear; mechanical waves traveling through a medium.
- 21. System — System that exchanges both matter and energy with its surroundings.
- 23. Energy — Energy related to heat; total kinetic energy of particles within a substance.
- 25. in Simple Machines — Useful work output ÷ total work input × 100; measures how effective a machine is.
- 28. — Do not create energy; instead, they transfer and transform energy, often trading force for distance.
