Physical objects are what we interact with on a daily basis, whether it be picking up a cup of coffee, unlocking a door, or typing on a keyboard. These objects can be mundane or fascinating, depending on the individual. What makes an object physical? Forces acting on the object cause it to move and deform, whether it's a metal bar that bends when struck with a hammer or a sheet of paper that is pressed against a typewriter key. In studying physical objects, we can learn about the laws of mechanics, the properties of materials, and how objects are formed.
