|---|---|---|---|---|---|
| Metal | Element that has luster, is malleable, and is ductile.
🗑
|
||||
| Nonmetal | Element that is usually a gas or brittle solid at room temperature and is a poor conductor of heat or electricity.
🗑
|
||||
| Atom | Smallest unit of matter; made up of protons, neutrons, and electrons.
🗑
|
||||
| Nucleus | The positively charged central core of an atoms, consisting of protons and neutrons and containing nearly all its mass.
🗑
|
||||
| Proton | Positively charged particle in the nucleus of an atom.
🗑
|
||||
| Neutron | A subatomic particle of about the same mass as a proton but without an electric charge.
🗑
|
||||
| Electron | A stable subatomic particle with a charge of negative electricity found in all atoms.
🗑
|
||||
| Law of Conservation of Mass | Matter can neither be created nor destroyed, it can only change form or be transferred.
🗑
|
||||
| Molecule | Smallest particle of a substance. Atoms make molecules.
🗑
|
||||
| Chemical Equation | An equation that has the changes in the arrangements of atoms during a chemical reaction.
🗑
|
||||
| Friction | When an object moves in one direction, sliding past another object, friction moves it in the opposite directions.
🗑
|
||||
| Thrust | Strong push that quickly moves an object.
🗑
|
||||
| Net Force | The combining of ALL forces on an object.
🗑
|
||||
| Force | A push or pull.
🗑
|
||||
| Balanced Force | All forces acting on an object are equal and opposite in direction. The net force equals 0 N and causes no change in motion.
🗑
|
||||
| Unbalanced Force | All forces acting on an object are NOT equal. The net force will NOT be 0 N and there will be a change in motion.
🗑
|
||||
| Inertia | An object's resistance to a change in its path of motion.
🗑
|
||||
| Speed | Distance traveled by an object in a given amount of time.
🗑
|
||||
| Velocity | An object speed in a given direction.
🗑
|
||||
| Acceleration | Change in an objects speed or direction over time.
🗑
|
||||
| Newton | SI unit of force
🗑
|
||||
| Newton's 1st Law | An object at rest stays at rest unless acted upon by an unbalanced force. An object in motion stays in motion unless acted upon by an unbalanced force.
🗑
|
||||
| Newton's 2nd Law | Acceleration of an object depends on its mass and the amount of force applied.
🗑
|
||||
| Newton's 3rd Law | For every reaction there is an equal and opposite reaction.
🗑

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.
