Prototype Unit 2

1. A quantity having direction as well as magnitude, especially as determining the position of one point in space relative to another. electricity A form of energy resulting from the existence of charged particles (such as electrons or protons), either statically as an accumulation of charge or dynamically as a current.
6. A rule of conduct or action prescribed or formally recognized as binding or enforced by a controlling authority.
10. Is the force required to cause a mass of one kilogram to accelerate at a rate of one meter per second squared in the absence of other force-producing effects.
11. Increase in the rate or speed of something.
12. The SI unit of mass (equivalent to approximately 2.205 lb), first introduced as a unit of mass for the metric system.
13. Is a carefully thought-out explanation for observations of the natural world that has been constructed using the scientific method, and which brings together many facts and hypotheses.
16. The size, length, or amount of something, as established by measuring.
18. A thorough or dramatic change in form or appearance.

2. (of a quantity) having only magnitude, not direction.
3. A coherent, typically large body of matter with no definite shape.
4. The maximum amount that something can contain.
5. The ability to do something or act in a particular way, especially as a faculty or quality.
7. A new method, idea, product, etc. grams A metric unit of mass equal to one thousandth of a kilogram.
8. A mathematical relationship or rule expressed in symbols.
9. A body's relative mass or the quantity of matter contained by it, giving rise to a downward force; the heaviness of a person or thing.
14. The push or pull on an object with mass causes it to change its velocity.
15. The speed of something in a given direction.
17. The amount or number of a material or immaterial thing not usually estimated by spatial measurement.
