| Motion | a change of position in a certain time |
| Force | a push, pull, kick, hit |
| Average Speed | total distance divided by total time |
| Velocity | the speed and the direction of a moving object |
| Acceleration | a measure of the change in velocity during a period of time |
| Friction | a force that acts in the opposite direction of motion |
| Mass | the amount of matter,stuff,(inertia) in an object |
| 9.8 m/s/s | the acceleration due to gravity on Earth |
| Weight | the measure of the force of attraction between objects |
| Inertia | the tendency to either stay at rest or stay in motion |
| Newton's First Law of Motion | an object at rest will remain at rest and an object in motion will remain in motion at constant velocity unless acted upon by an outside force |
| Newton's Second Law of Motion | F=ma |
| Newton's Third Law of Motion | for every action force, there is an equal and opposite reaction force |
| Balanced Forces | the forces acting on an object cancel each other out resulting in no movement |
| Unbalanced Forces | one force acting on an object is greater than others which produces a change in motion |
| The inertia of an object is a measure of its | mass |
| Potential Energy | energy an object has because of it's shape or the position of a group of objects. |
| Gravitational Potential Energy | energy of an object because of it's height from Earth's surface |
| Stored potential Energy | energy that can happen, elasticity, battery, spring, |
| Kinetic Energy | energy something has because of its motion |
| conservation of Energy | energy can be changed from one form to another but Energy always exist. |
| Energy | The ability to do work |
| greenhouse effect | trapping radiating heat and warming of the area |
| Heat | a part of energy that flows from higher temperatures to lower temperatures |
| work | the Force applied to an object/distance the object moves in the direction of the force |
