To understand why this shows an energy transfer, we need to look at the concept of work. Work is defined as the transfer of energy to an object in order to move it or cause a change in its position, state, or structure.
In this case, Sandra's dad exerted a force on the grocery cart by pushing it. This force caused the cart to move, which means that energy was transferred to the cart. The energy transfer occurred because Sandra's dad applied a force over a distance, and this work resulted in the cart gaining kinetic energy.
Therefore, when Sandra's dad pushed the grocery cart and made it start moving, it demonstrated an energy transfer to an object.
