Across
- 3. – measures how fast an object is moving (speed) AND the direction in which it is moving
- 4. change - a usually irreversible chemical reaction involving the rearrangement of one or more substances and a change in their chemical properties, resulting in the formation of at least one new substance: The formation of rust on iron is a chemical change.
- 7. force - always causes a change in motion. Is not equal and opposite. Net force is GREATER than zero.
- 8. – the transfer of energy by electromagnetic waves. The sun is Earth’s main source of electromagnetic waves.
- 10. a material that heat can move through easily like aluminum steel and other metals
- 12. - two or more substances are mixed together but not combined chemically
- 17. energy- stored energy in a body or system due to it's position
- 18. push or pull
- 19. – the tendency for an object to keep doing what it is doing (resting or moving)
- 20. – the changes in an object’s motion. This can be speeding up, slowing down or changing direction. An object’s acceleration depends on the object’s mass and the force applied.
Down
- 1. force that attracts (pulls) all object's to the center of the earth
- 2. exact location of an object
- 5. the action or influence of people, groups, or things on one number
- 6. – the amount of matter (“stuff”) - in an object.
- 9. – the transfer of thermal (heat) energy by the movement of liquids or gases.
- 11. - the amount of force (pull) that gravity has on an object's mass. Your weight depends on the gravitational pull of your location.
- 13. flow of the thermal (heat) energy between things that are touching
- 14. the ability to do work
- 15. measures how fast an object is moving in a given amount of time
- 16. energy- energy of motion
