Sandra and her dad go to the grocery story. As they do their shopping, Sandra's dad asks her about her homework. Sandra remembers that she is supposed to make a list of "real world" examples of energy transfer. Which of the following could be included on a list of examples showing an energy transfer to an object? (2 points) This DOES show an energy transfer to an object. This does NOT show an energy transfer to an object. Sandra's dad pushes the grocery cart to make it start moving. Sandra sees a new kind of breakfast pastry sitting on a high shelf. Sandra slides a gallon of milk out of the way to get a colder gallon from the back of the shelf. Sandra's dad stands still while he thinks about what is on the grocery list. Skip to navigation

Answer 1

Here are the evaluations of the scenarios provided:

1. Sandra's dad pushes the grocery cart to make it start moving.

   • This DOES show an energy transfer to an object. (Energy is transferred from Sandra's dad to the grocery cart, causing it to move.)

2. Sandra sees a new kind of breakfast pastry sitting on a high shelf.

   • This does NOT show an energy transfer to an object. (There is no energy transfer involved in simply observing the pastry.)

3. Sandra slides a gallon of milk out of the way to get a colder gallon from the back of the shelf.

   • This DOES show an energy transfer to an object. (When Sandra slides the gallon of milk, she is applying force, which transfers energy to the gallon of milk.)

4. Sandra's dad stands still while he thinks about what is on the grocery list.

   • This does NOT show an energy transfer to an object. (Standing still does not involve any energy transfer to objects.)

In summary, the scenarios demonstrating energy transfer are: "Sandra's dad pushes the grocery cart" and "Sandra slides a gallon of milk."
