Question | Answer |
Atom | the smallest particle in which an element can be divided and still have the same chemical properties |
element | a substance that cannot be broken down into a smaller substance |
atomic number | number of protons in the nucleus of a given element |
product | substance that forms as a result of a chemical reaction |
reactant | substance that exists before a chemical reaction |
chemical equation | shorthand form for writing what reactants are used and what products are formed in a chemical reaction; sometimes shows whether energy is produced or absorbed |
density | the mass of an object divided by its volume |
triple beam balance | measures the mass of an object |
graduated cylinder | measures volume |
ruler | measures the length of a given object |
volume | the amount of space that an object occupies |
balanced force | occurs when the net force on an object equals zero and the objects motion does not change |
unbalanced force | occurs when the net force on an object does not equal zero and there is a change in motion |
Newton's First Law | an object at rest will stay at rest, while an object in motion will stay in motion unless acted upon by an unbalanced force |
Newton's Second Law | the acceleration of an object by its force is inversely proportional to mass of the object and directly proportional to the force |
Newton's Third Law | for every action there is an equal and opposite reaction |
force | a push or pull |
speed | distance traveled by an object in a given amount of time |
velocity | an object's speed in a given direction |
acceleration | a change in an object's speed or direction overtime |
