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