Term
| What are some examples of translational motion? |
|
Definition
| Linear motion, circular motion, and projectile motion. |

|
Term
| When does translational motion occur? |
|
Definition
| Translational motion occurs when the object moves through space. |
|
|

Term
| What is a motion diagram? |
|
Definition
| An image of several layered frames, showing an object's position at several equally spaced instants of time. |
|
|
Term
| How can we tell if an object is moving at a constant speed in a motion diagram? |
|
Definition
| The images are equally spaced. |
|
|
Term
| How can we tell if an object is speeding up in a motion diagram? |
|
Definition
| There is an increasing distance between the images. |
