QuestionAnswer
Balanced Force A balanced force is when two equal forces are applied on an object pushing both ways. Also they are equal forces acting on an object in opposite directions

Groups number of valence electrons
Physical Change are changes affecting the form of a chemical substance, but do not change the chemical composition of that substance.
Atom is a basic unit of matter that consists of a dense central nucleus surrounded by a cloud of negatively charged electrons
Chemical Equations consists of the chemical formulas of the reactants (the starting substances) and the chemical formula of the products (substances formed in the chemical reaction).
Speed The rate or a measure of the rate in motin
Newton's first law If an object experiences no net force, then its velocity is constant: the object is either at rest (if its velocity is zero), or it moves in a straight line with constant speed (if its velocity is nonzero).
Rows period
Acceleration is the rate at which the velocity of a body changes with time
Density p=m/v
Flask laboratory glassware for holding larger volumes than simple test tubes
test tube also known as a culture tube or sample tube, is a common piece of laboratory glassware consisting of a finger-like length of glass or clear plastic tubing, open at the top, usually with a rounded U-shaped bottom
goggles safety glasses are forms of protective eyewear that usually enclose or protect the area surrounding the eye in order to prevent particulates, water or chemicals from striking the eyes
triple beam balance measures grams
velocity rapidity of motion
force a push or pull
newton unit of force equal to the force needed to accelerate 1kg or 1m per sec.
direction the act or function of directing
thrust strong push that quickly moves an object
