| Question | Answer |
|---|---|
| Factor that changes as a result of changes in the other variables. | Dependent Variable |
| Factor that as it changes affects the measure of another variable. | Independent Variable |
| A variable that does not change when other variables change. | Constant |
| Standard used for comparison of test results in an experiment. | Control |
| Explanation of things or events that is based on knowledge gained form many observations and investigations. | Theory |
| Statement about what happens in nature that seems to be true all the time; does not explain why or how something happens. | Scientific Law |
| Rate of change in velocity | Acceleration |
| a push or pull exerted on an object. | force |
| Resistance of an object to a change in its motion. | Inertia |
| The speed and direction of a moving object. | Velocity |
| Distance an object travels per unit of time. | Speed |
| States that the acceleration of an object is in the same direction as the net force on the object, and that the acceleration equals the net force divided by the mass. | Theory |
| Statement about what happens in nature that seems to be true all the time; does not explain why or how something happens. | Scientific law |
| Stored energy an object has due to its position. | force |
| Resistance of an object to a change in its motion. | Inertia |
| meters per second | Speed |
| The speed and direction of a moving object. | Mechanical Energy |
| States that an object moving at a constant velocity keeps moving at that velocity unless an unbalanced net force acts on it. If an object is at rest, it stays at rest unless an unbalanced net force acts on it. | Newton's 1st Law of Motion |
| Machine that does work with only one movement. | Simple Machine |
| Distance an object travels per unit of time. | Speed |
| States tat when one object exerts a force on a second object, the second object exerts force on the first object that is equal in strength and in the opposite direction. | Newton's 3rd Law of Motion |
| force that opposed the sliding motion between two touching surfaces. | Friction |
| Transfer of thermal energy by collisions between particles in matter at a higher temperature and particles in matter at a lower temperature. | Conduction |
| States that the acceleration of an object is in the same direction as the net force on the object, and that the acceleration equals the net force divided by the mass. | Newton's 2nd Law of Motion |
| Transfer of thermal energy by electromagnetic waves. | Radiation |
| States that energy can never be created or destroyed. | Law of Conservation of Energy |
| material such as copper wire, in which electrons can move easily | Conductor |
| sum of the potential energy and kinetic energy in a system. | Temperature |
| Energy a moving object has because of its motion | Kinetic Energy |
| meters | Length |
| Stored energy an object has due to its position. | Potential Energy |
| Machine that is a combination of two or more simple machines. | Volume |
| Mass per unit volume of a material. | Density |
| Ratio of the output work done by the machine to the input work done of the machine, expressed as a percentage. | Efficiency |
| sum of the potential energy and kinetic energy in a system. | Mechanical Energy |
| Seconds | Time |
| Kelvin | Temperature |
| kilograms | Mass |
| cubic meter | Volume |
| kilogram per cubic mete | Density |
| joule | Temperature |
| joule | Energy |
