Engineers use energy in smart ways to build machines that make our daily lives easier. Let’s break down some important ideas:
Efficiency: Engineers try to make machines that use energy well. This helps to waste less energy. For example, in electric cars, the energy from the battery is used in the best way to help the car move.
Work and Power: Engineers figure out how much work is done. Work can be explained simply as: Work = Force × Distance. This means how hard you push something and how far you move it.
Types of Machines: There are different types of machines like levers, pulleys, and gears that change energy from one form to another. For example, a pulley system can help lift heavy things with less effort from a person.
By learning these ideas, engineers come up with cool new machines that make our lives better!
