Term | Definition |
---|---|
Isotope | An Isotope is a variation of the same element that has more or less neutrons in it. |
Ion | An Ion is a variation of the same element that has more or less electrons in it. |
neutron | A neutron is a part of an atom, located in the nucleus that has a neutral or no charge. |
Electron | An electron is a part of an atom, located on the electron shell that has a negative charge. |
Electron Shells | The electron shell are rings that circle around a nucleus in an atom; this is where the electrons are located |
Triple Beam Balance | A triple beam balance is a science tool that measures the amount of mass in an object. |
Hand Lens | A hand lens is a science tool that helps you see better with you naked eye. |
Petri Dish | A petri dish is a science tool used for growing and viewing micro-organisms. |
Flask | A Flask is a science tool that is used for holding or mixing chemicals. |

Newtons 1st law | An object in motion stays in motion unless, and an object at rest stays at rest unless acted upon by an outside force. |
Newtons 3rd law | For every action there as an equal and opposite reaction. |
Newtons 2nd law | Acceleration depends on the mass and the force exerted on an object. |
Unbalanced force | An unbalanced force is when the amount of force exerted on an object is more than 0 Newtons. |
Balanced force | A balanced force is when the amount of force being exerted on an object is 0. |
Speed | speed is distance traveled by an object in a certain amount of time. |
Velocity | Velocity is an objects speed and direction at a given instant. |
Acceleration | Acceleration is a change in an objects velocity (speed and/or direction.) |
Force | A force is a push or pull. |
Newton | A Newton is the unit that force is measured in. |
