Across
- 1. The ability to do work or cause change. It comes in different forms, like kinetic, potential, and thermal _____.
- 2. The energy an object has due to its motion. The faster something moves, the more _____ energy it has.
- 6. The total energy (both kinetic and potential) an object has due to its motion and position.
- 8. Energy stored in substances. When a substance reacts, it releases energy, like in batteries or food.
- 9. A type of stored energy found in objects that can be stretched or compressed, like a rubber band or a spring.
- 10. The transfer of energy that happens when a force is applied to an object, making it move in the direction of the force.
- 13. The energy of moving particles in a substance. The more heat an object has, the faster its particles move, and the more _________ energy it has.
- 14. The stored energy an object has because of its position or condition. For example, a stretched rubber band has potential energy.
Down
- 1. This type of energy powers things like lights, computers, and phones.
- 3. A unit of energy equal to 1,000 joules.
- 4. A type of potential energy an object has because of its height above the ground. The higher an object is, the more ______energy it has.
- 5. The unit used to measure energy and work in physics. One _________ is the amount of energy used to move an object with a force of one newton over one meter.
- 6. The amount of matter in an object, measured in kilograms or grams. It does not change, no matter where the object is.
- 7. The force of gravity acting on an object’s mass.
- 11. carried by light or electromagnetic waves. The sun’s rays, X-rays, and microwaves are examples of _________ energy.
- 12. A push or pull on an object that can make it start moving, stop moving, or change direction.
