|---|---|---|---|---|---|
| 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
🗑
|
||||
| Unbalanced Force | Unbalanced forces: Forces that produce a non-zero net force, which changes an object's motion.
🗑
|
||||
| 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
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
