Video Summary

Physical changes are changes in the size, shape, or appearance of an object. They can be caused by a variety of factors, including growth, aging, and environmental changes. Physical changes are often reversible, meaning that the object can return to its original state. Some common examples of physical changes include: * Growth: A child growing taller is an example of a physical change. * Aging: A person's hair turning gray is an example of a physical change. * Melting: Ice melting into water is an example of a physical change. * Rusting: Iron rusting is an example of a physical change. Physical changes are important because they can affect the way an object functions. For example, a car that has been in an accident may have physical damage that prevents it from running properly. Physical changes can also be used to identify an object. For example, a fingerprint is a unique physical characteristic that can be used to identify a person.
