8th Physical Science
Term | Definition |
---|---|
Qualitative | Made by gathering information that can be recorded using descriptive language. |
Quantitative | Made by gathering information that can be recorded as a number with a measurement unit. |
Inference | Not a fact, but an interpretation of what the direct observations mean. |
Scientific Law | Describes what scientists expect to happen every time under a particular set of conditions. |
Constant | Part of an experiment that is held in the same condition for control and experimentation. |
Variable | Part of an experiment that changes. |
Manipulative variable | A factor in a controlled experiment that is intentionally changed by the experimenter |
# 8 | |
Question | To ask for information. |
Responding Variable | A resulting factor in a controlled experiment that is observed and measured to see if it changes due to the manipulation of another variable. |
Experiment | A course of action completed in order to test a hypothesis. |
Control | A standard to which all other levels are compared in a scientific experiment. |
Physical Properties | Characteristics of a pure substance that can be observed without changing into another substance. |
Chemical Properties | A pure substance that cannot be broken down into other substances by chemical or physical. |
Weight | A measure of the force of gravity on an object. |
Mass | The amount of matter in an object. |
Work | |
Newton | A unit of force required to move 1 kilogram 1 meter squared. |

Newton's Law 1 | An object at rest stays at rest or an object that is moving at a velocity in a straight line keeps moving at that velocity unless another object acts on it. |
Newton's Law 2 | The amount of force needed to make an object change it's speed depends on the mass of the object and the acceleration required. |
Newton's Law 3 | For every action there is an equal and opposite action. |
Mechanical Advantage | The ratio of the output force produced by a machine to the applied input force. |
