push or pull that acts on an object
force
the ability to do work or cause change
energy
electrons at the highest energy levels that are involved in chemical bonding
valence electrons
substance with a ph less than 7
acid
newton's first law of motion
an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
a force that requires two pieces of matter to touch
contact force
energy of a moving object
kinetic energy
type of bond formed when atoms lose or gain electrons
ionic bonds
substance with a ph more than 7
base
group of elements that are stable and therefore least likely to react
noble gases
force that results when two materials rub against each other
friction
energy that results from the position or shape of an object
potential energy
type of bond formed when atoms share electrons
covalent bond
substance with a ph equal to 7
neutral
law of conservation of energy
energy cannot be created or destroyed, only transferred
force of attraction between any two objects
gravity
energy stored in an atom's nucleus
nuclear energy
atoms share 2 pairs of electrons
double bond
substance that is dissolved in a solution
solute
type of energy found in the nucleus of atoms
nuclear energy
any change in the speed or direction of an object's motion
acceleration
form of energy associated with the motion, position, or shape of an object
mechanical energy
atoms share 3 pairs of electrons
triple bond
substance that dissolves the solute
solvent
how do you neutralize a strong acid?
add the same amount of a strong base
