8th Topic 3 Energy
Across
- 3. The rate at which work is done or energy is transferred; measured in Watts (W), where 1 W = 1 J/s.
- 6. Energy stored in an object due to its height above the ground.
- 10. energy is measured in this unit
- 11. Energy stored in objects that can be stretched or compressed, like springs or rubber bands.
- 14. Radiant energy that travels through space in waves, such as UV, radio, or microwaves.
- 17. A push or pull applied to an object; described by its strength and direction, measured in Newtons (N).
- 18. The more ME an object has, the more _____ it can do
- 21. A principle stating that energy may change form, but it cannot be created or destroyed under ordinary conditions.
- 22. The total amount of kinetic and potential energy in a system; associated with motion, position, or shape.
- 24. Energy that is stored; can be gravitational or elastic.
- 25. Energy of electrical charge; can be kinetic (like lightning) or potential (like batteries).
Down
- 1. The ability to do work or cause change; it is transferred and measured in Joules (J).
- 2. Potential energy stored in an atom's nucleus.
- 4. The result of a force causing an object to move; calculated as force (N) multiplied by distance (m), measured in Joules (J).
- 5. All forms of E can be ___________ into other forms
- 7. kinetic energy depends upon the ____ of the object and its ____
- 8. if a net force is greater than 0N then the forces are ____ and there will be movement
- 9. if a net force is 0N we can say the forces are _____ and there will be not motion
- 12. Energy stored in chemical bonds, like in food or fuel.
- 13. a Nm is the same as a ____
- 15. Total kinetic and potential energy of the particles in an object; related to the temperature of matter.
- 16. When an object changes its position relative to another object.
- 19. Energy in the form of motion; depends on the mass and speed of a moving object.
- 20. a measure of power- is equal to one J/sec
- 23. The overall force when two or more forces act on an object at the same time; can be balanced, unbalanced, or combined.
