| No matter what planet I am on, my 1) ________________ stays the same. However, my 2)______________ will change due to the different pull of gravity on each planet. | 1) mass 2)weight |
| The ability to do work (ie. the transfer of energy that causes change) is called________________. | energy |
| A moving bicycle, a ball rolling down a hill, and any other time potential and kinetic energy work together, are all examples of _______________ ___________. | mechanical energy |

| There are two primary forms of energy, 1)______________ energy, the energy of MOTION, and 2)____________ energy, energy that is STORED. | 1) kinetic 2) potential |
| Due to thermal energy, a pot of boiling water has _________ energy than an equal amount of ice water. | more |
| A pulled rubber band, a tensed muscle, and the spring inside your pen, are all examples of_______________. | elastic energy |
| As we eat, our body converts the ________________ _____________ in our food into thermal energy, electrical energy, and mechanical energy. | chemical energy |
| Forces on an object that result in a change in the motion of the object are called: | unbalanced force |
| The sum of all the forces acting on an object | net force |
| The position of an object and the direction of forces are describes relative to a _________________ ___________. | reference frame (reference point) |
| A measure of how much matter is present in a substance | mass |
| A straight path that an object moves along | direction |
| ANY change in velocity, including speeding up, slowing down, or changing direction, is called_____________________________________. | acceleration |

| Objects that affect one another | Interacting Objects |
| A measure of how much matter is present in a substance | Mass |
| The heaviness of an object; the force of gravity between two objects with mass | Weight |
| A push or pull that can change the motion of an object | Force |
| The change in an object’s position with respect to time and in comparison with the position of other objects used as reference points | Motion |
| A system that uses coordinates or background objects to establish position or to measure movement of a point in space | Frame of Reference |
| The rate of displacement from the reference point. Distance divided by time. | Speed |
| Speed in a given direction | Velocity |
| Friction is a force that opposes motion | Friction |
| The tendency of a moving object to continue in a straight line or a stationary object to remain in place. | Inertia |
| An object at rest tends to stay at rest. An object in motion stays in motion in a straight line until a force acts upon it | Newton’s 1st Law of Motion: AKA The Law of Inertia |
| Force equals mass times acceleration. | Newton’s Second Law of Motion: AKA The Mathematical Law |
| For every action there is an equal and opposite reaction | Newton’s Third Law of Motion: AKA The Equal and Opposite Law |
