| What is mass | Mass is the amount of matter that makes up an object |
| What is force | Force is a push or a pull |
| What is froction | Friction is a force that causes objects in motion to speed up or slow down when 2 surfaces rub together |
| What is speed | speed is a measure of how fare on object moves in a certain amount of time |
| Motion | A motion a movement, or a change in an object's position |
| Position | Position is that place where an object is located |
| Gravity | Gravity is a force that pulls things toward Earth. |
| What happens when more friction presents | The object in motion slows down. |
| How much force do you have to put on a light object for it to be in motion | you don't need to put a lot of force for it to be in motion |
| What happens if you put a lot of force on something. | The more energy is released. |
| Farce makes things_____ up slowdown of change ______Without a force a still object remains still& a moving object would keep moving. | Speed, direction |
| The more force that is applied, the ________ the object will go. | farther |
| Unbalanced force happens when one side has ________ force in one direction. This will cause the object to ______ in the direction the greater force is going. | Greater, Move |
