| Physicist | scientist who studies all the different forces at work in the world |
| Physics | the study of natural phenomena |
| Force | Any push or pull that causes an object to start, stop, or change speed, direction, or shape. |
| Energy | the ability to do work |
| Kinetic Energy | the energy of motion |
| Potential Energy | energy that is stored to be used later |
| Friction | resistance to motion created by two objects moving against each other. Friction makes heat. |
| Speed | How fast and how far an object moves in a certain amount of time. The speed of an object defines the rate of change |
| Motion | a change in the direction, position, or speed of an object |
| Matter | anything that has mass, takes up space, and show the property of inertia |
| Mass | how much matter (stuff) an object has |
| Physical Properties | characteristics of objects that can be described using the five senses |
| Chemical Properties | Characteristics that describe the way a substance may change or react to form other substances. |
| Newton's 3rd Law of Motion | For every action, there is an equal and opposite reaction. |
| Netwon's 2nd Law of Motion | The greater the force the greater the change in motion will be. |
| Newton's 1st Law of Motion | The more massive an object, the harder it is to force it to move. |
| Come in pairs | Forces |
| Gravity | A pulling force between objects. The more massive the object, the stronger the pull. |
| Inertia | An object's resistance to change in its speed or direction. |
