Work is being done.

The student and the ball are both doing work because they changed their position and are in motion.

​​Position and Motion

• An object’s position refers to its place or location.  ​

• ​Motion is when an object’s position changes compared to the objects it is around. 

​

Example: If a bird flies away from a tree, the bird’s position changed in comparison to the tree.
