Final answer:
A lawnmower is a product that falls under the category of Business. It can gain energy when powered or fueled, and it loses energy when used to cut grass or due to friction between its moving parts.
Step-by-step explanation:
The lawnmower is a product that falls under the category of Business. It is considered a product because it is an item that is bought and sold in the market. In this case, the man bought the lawnmower to use for his landscaping business, indicating that it is a tool or asset he will utilize in his business operations.
When it comes to gaining or losing energy, a lawnmower can gain energy when it is being powered or fueled, such as when it is connected to a power source or filled with gasoline. This energy is then converted into kinetic energy to make the blades rotate and cut the grass.
On the other hand, a lawnmower can lose energy when it is used to cut grass. The energy is transferred from the mower to the grass as it cuts, resulting in a decrease in the mower's energy. Additionally, friction between the moving parts of the lawnmower can also cause a loss of energy.
