Molly is planting a flower garden. She carries the flowers from the car to the garden. She then pulls each flower out of its pot. She shoves a shovel into the dirt and digs a hole. She then holds the flowers as she places each of them in a hole.
In which case is Molly doing work? Remember, works is when an object moves as a result of force (a push of a pull). There are 2 answers! TWO ANSWERS!
When Molly carries the flowers from the car to the garden.
When Molly pulls the flowers from their pots.
When Molly lowers the flowers into their holes.
When Molly digs a hole.
