Term | Definition |
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. |
