Question

If a girl carries groceries up a flight of stairs, is she doing work on the groceries? Explain.​

Answer 1

Step-by-step explanation:

Yes she is doing work. With or without the groceries, she is still doing work. She does more work with the groceries than without because Work is defined by F which is defined by mass. The mass increases with the groceries.

The work done is against the force of gravity.
