Ask a Science Student, Part 2: Physics
By Matt Radford ’16
Energy has many different forms. Electrical, thermal, and mechanical kinetic energy are all forms associated with moving objects. Potential energy is dependent on an object’s position in a field, such as apples hanging in a tree, or an object’s position relative to its parts, such as a drawn longbow. An apple also has digestible energy, usually measured in calories. Other units of energy commonly found in day-to-day life include the watt-hour, which probably shows up on your electricity bill, and the British Thermal Unit, which is likely mentioned on any air conditioning unit.
