| 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 |
| 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 |
| In an experiment, a variable that does not change when other variables change. | Constant |
| In an experiment, 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 from many observations and investigations. | Scientific Law |
| A push or pull exerted on an object. | Theory |
| Explanation of things or events that is based on knowledge gained from many observations and investigations. | Acceleration |
| Statement about what happens in nature that seems to be true all the time; does not explain why or how something happens. | Scientific Law |
| Statement about what happens in nature that seems to be true all the time; does not explain why or how something happens. | Scientific Law |
| A push or pull exerted on an object. | Force |
| States that an object moving at a constant Velocity keeps moving at that velocity unless an unbalanced net force acts on it. | Acceleration |
| Resistance of an object to a change in its motion. | Newton's 2nd Law of Motion |
| A push or pull exerted on an object. | Force |
| The speed and direction of a moving object. | Velocity |
| Resistance of an object to a change in its motion. | Kinetic Energy |
| The speed and direction of a moving object. | Potential Energy |
| The speed and direction of a moving object. | Velocity |
| Distance an object travels per unit of time. | Speed |
| Distance an object travels per unit of time. | Speed |
| Distance an object travels per unit of time. | Speed |
| Ratio of the output work done by the machine to the input work done on the machine, expressed as a percentage. | Newton's 1st Law of Motion |
| Ratio of the output force exerted by a machine to the input force applied to the machine. | Mechanical Advantage |
| Transfer of thermal energy by collisions between particles in matter at a higher temperature and particles in matter at a lower temperature. | Newton's 1st Law of Motion |
| 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 |
| States that when one object exerts a force on a second object, the second object exerts a force on the first object that is equal in strength and in the opposite direction. | Newton's 3rd Law of Motion |
| States that when one object exerts a force on a second object, the second object exerts a force on the first object that is equal in strength and in the opposite direction. | Newton's 3rd Law of Motion |
| Force that opposes the sliding motion between two touching surfaces. | Insulator |
| Energy a moving object has because of its motion; depends on the mass and speed of the object. | Kinetic Energy |
| Force that opposes the sliding motion between two touching surfaces. | Friction |
| Stored energy an object has due to its position. | Length |
| Energy a moving object has because of its motion; depends on the mass and speed of the object. | Mass |
| Amount of space occupied by an object. | Law of Conservation of Energy |
| Stored energy an object has due to its position. | Potential Energy |
| Transfer of energy that occurs when a force makes an object move; measured in joules. | Mechanical Energy |
| Joules | Law of Conservation of Energy |
| A push or pull exerted on an object. | Simple Machine |
| Distance an object travels per unit of time; meters per second;meters per second. | Mechanical Energy |
| Rate of change of velocity; can be calculated by dividing the change in the velocity by the time it takes the change to occur. | Simple Machine |
